PER CURIAM:

Both of the following dispositions command support of a majority of the court. For the reasons assigned in these alternate resolutions, the decision of the district court on the motion to suppress is reversed and the matter is remanded.

PART I

POLITZ, Circuit Judge:

In November, 1977, Jo Ann Williams was indicted in the Northern District of Georgia on two counts of possession of heroin with intent to distribute in violation of 21 U.S.C. § 841(a)(1). Before jeopardy attached, the district court granted her motion to suppress evidence of all heroin that had been seized from her. On appeal by the government pursuant to 18 U.S.C. § 3731, the panel majority affirmed, 594 F.2d 86 (5th Cir.). We directed rehearing en banc on our own motion, 594 F.2d 98 (5th Cir.). We now reverse and remand.

The History

In June, 1976, Special Agent Paul J. Markonni of the Drug Enforcement Administration (DEA) arrested Williams in Toledo, Ohio, for possession of heroin in violation of 21 U.S.C. § 841(a)(1). In March, 1977, after the District Court for the Northern District of Ohio denied her motion to suppress evidence of the heroin, she pleaded guilty and was sentenced to three years imprisonment. She then appealed the denial of her motion to suppress to the Sixth Circuit. The district court ordered Williams released pending appeal. A condition of the order releasing her was that she remain in Ohio.

During the evening of September 28, 1977, Markonni, on assignment at the Atlanta International Airport, recognized Williams as she departed a nonstop flight from Los Angeles. He was aware of the court order requiring that she remain in Ohio. He approached her, identified himself and asked her for identification. Williams produced the same Michigan driver's license she had shown Markonni when he arrested her the prior year in Ohio. She also produced an airline ticket that showed she was about to depart for Lexington, Kentucky. Markonni asked whether she had permission to travel outside Ohio. Williams said, "No, this is the first time." When asked why she was going to Lexington, she said, "I live there now."

Markonni arrested Williams for violating the travel restriction of her release order and took her to the airport police office. A search of her person made incident to the arrest uncovered a packet of heroin in her coat pocket. Markonni then arrested Williams for violation of the Controlled Substances Act, 21 U.S.C. § 801 et seq.

Markonni took the baggage claim checks from Williams' ticket envelope and retrieved two pieces of luggage she had checked from Los Angeles to Lexington. After Williams refused to consent to a search of the bags Markonni secured them in the airport police office. The following morning Markonni requested a search warrant from a federal magistrate. The Affidavit for Search Warrant that Markonni executed described the luggage and stated that he had reason to believe it contained heroin. He detailed the basis for this belief by giving a sketch of the prior history and the incident at the Atlanta airport. The magistrate issued the warrant and the resultant search revealed a large quantity of heroin.

The Motion To Suppress

The November, 1977, indictment contained two counts, one based on the heroin found on Williams' person and the other based on the heroin found in her luggage. She moved to suppress all evidence of the heroin. She contended that her arrest upon deplaning was unlawful, therefore evidence of the heroin seized from her person during the search made incident to that arrest should be suppressed. She also contended the search warrant was invalid because its issuance was based in critical part on the information about the heroin found on her person. Accordingly, she argued, evidence of the heroin found in the luggage should be suppressed.

A magistrate heard the motion and concluded the arrest was lawful, the search incident to the arrest was proper, the search warrant appropriately issued and the luggage search was legal. The district court rejected the magistrate's recommendations and sustained the motion, suppressing all evidence of the heroin. The panel majority affirmed.

Arrest Powers

Williams grounds her argument that her arrest was invalid on 21 U.S.C. § 878(3), which describes the power of DEA agents to make warrantless arrests as follows:

Any officer or employee of the Drug Enforcement Administration designated by the Attorney General may —

* * * * * *

(3) make arrests without warrant (A) for any offense against the United States committed in his presence, or (B) for any felony, cognizable under the laws of the United States, if he has probable cause to believe that the person to be arrested has committed or is committing a felony . .

The government's brief to the panel advanced two theories in support of its argument that the challenged arrest was authorized by this statute. The first was that Markonni had probable cause to make a warrantless arrest for bail jumping under 18 U.S.C. § 3150. The government did not pursue this argument before the en banc court. Like the panel, we reject it.

The government's second theory is that Williams' violation of the conditions of her bond is an offense proscribed by 18 U.S.C. § 401(3) or by 18 U.S.C. § 3146, or by both. The government contends that, because this offense was committed in Markonni's presence, § 878(3)(A) authorized the warrantless arrest. The panel rejected this argument.

The panel held: "A court, not a DEA agent, is empowered by 18 U.S.C. § 401(3) to punish disobedience or contempt of its order by fine or imprisonment." 594 F.2d at 92. From this premise the panel concluded that "DEA agents, therefore, have no implied arrest power under section 401." 594 F.2d at 93. The panel also held that 18 U.S.C. § 3146 did not empower Markonni to arrest Williams, being of the opinion that a violation of a bond condition is not a criminal violation per se. The panel concluded that a violation of a bond condition imposed under § 3146 "merely sets the judicial machinery in motion and empowers a court, not a DEA agent, to determine whether punitive action is warranted." 594 F.2d at 94.

The Issue

The issue before us might best be brought into focus by the posing of seriatim inquiries:

1. Is the violation of a travel restriction imposed by the court, when granting a release pending appeal, an act of contempt under 18 U.S.C. § 401(3)?

2. If it is contempt, is it or may it be criminal contempt?

3. If it is criminal contempt, is it an offense against the United States within the intendment of 21 U.S.C. § 878(3)?

4. Finally, if an offense, is it necessary for the court to act before an arrest may be made for this offense?

Capsulating the foregoing, the issue before us, then, is: Did agent Markonni legally arrest Williams for breach of the court imposed travel restriction in the absence of any initiating request or direction by the court? The panel majority concluded that Markonni could not effect a valid arrest under these circumstances. We conclude otherwise.

The Offense — The Winding Road

The journey to our conclusion that the breach of the travel restriction is an offense against the United States for which agent Markonni could arrest Williams required a sorting out and alignment of the history of contempt of court and certain of the pertinent statutory and jurisprudential developments. We shall not attempt an exhaustive discussion of that review but, rather, refer to the authorities cited infra.

Our journey begins with the threshold recognition that the willful breach of a court order imposing a condition of release pending appeal constitutes a contempt of court. Universally and historically, and by the very words of 18 U.S.C. § 401(3), disobedience or resistance to a court's lawful order is contempt of court.

Contempt — A Crime

Contempt has been viewed since time immemorial as a crime. Blackstone unqualifiedly and repeatedly referred to contempt as a crime, as indeed it had been traditionally regarded and punished at common law. 4 Blackstone's Commentaries, 1-6, 119-126, 280-287.

The Supreme Court has long recognized that contempt is a crime. The exact positioning of contempt in the panoply of the criminal law, as earlier alluded to, has been the subject of much confusion, inquiry and dispute. However, one beacon light shines throughout: criminal contempt is and always has been considered a crime. Mr. Justice Holmes declared in Gompers v. United States, 233 U.S. 604, 610, 34 S.Ct. 693, 695, 58 L.Ed. 1115 (1914):

These contempts are infractions of the law, visited with punishment as such. If such acts are not criminal, we are in error as to the most fundamental characteristic of crimes as that word has been understood in English speech.

In the celebrated case of Green v. United States, 356 U.S. 165, 201, 78 S.Ct. 632, 652, 2 L.Ed.2d 672 (1958), Mr. Justice Black (in dissent) echoed the foregoing observation by Mr. Justice Holmes and added:

As it may now be punished criminal contempt is manifestly a crime by every relevant test of reason or history. It was always a crime at common law punishable as such in the regular course of the criminal law.

In a very scholarly fashion Mr. Justice White traced the torturous history of contempt and the constitutional evolution of the disposition of such charges in Bloom v. Illinois, 391 U.S. 194, 88 S.Ct. 1477, 20 L.Ed.2d 522 (1968). He concluded that statement quoted below by declaring that "criminal contempt is a crime in every fundamental respect" ( 391 U.S. at 201, 88 S.Ct. at 1481-82):

Criminal contempt is a crime in the ordinary sense; it is a violation of the law, a public wrong which is punishable by fine or imprisonment or both.

* * * * * *

Criminally contemptuous conduct may violate other provisions of the criminal law; but even when this is not the case convictions for criminal contempt are indistinguishable from ordinary criminal convictions, for their impact on the individual defendant is the same. Indeed, the role of criminal contempt and that of many ordinary criminal laws seem identical — protection of the institutions of our government and enforcement of their mandates.

One of the principal factors setting contempt apart from other crimes, as one reacts to and attempts to analyze the matter, is that the court may initiate the process leading to punishment. In other instances in the criminal justice area the prosecutor is the initiator. Does the fact that the court may initiate proceedings preclude action by the prosecutor? Does the fact that the court may initiate proceedings substantively affect the question before us?

Action By The Court — By The Prosecutor

Because of the nature of the offense, and particularly because of the involvement of the court, criminal contempt has been accorded treatment different from other criminal conduct. For example, Rule 42 of the Federal Rules of Criminal Procedure specifically addresses the disposition of criminal contempt, both on a summary basis and upon notice and hearing. However, this Rule does not purport to vest exclusive authority to initiate contempt charges in the courts. It is merely procedural. The Supreme Court recognized this in Bloom, supra, 391 U.S. at 205, 88 S.Ct. at 1484, when it noted that Rule 42 sets forth "many of the procedural protections available to criminal contemnors."

The prosecutor has authority to act in these matters. Criminal contempt charges may be initiated by indictment. United States v. Leyva, 513 F.2d 774 (5th Cir. 1975); Steinert v. United States District Court for the District of Nevada, 543 F.2d 69 (9th Cir. 1976); United States v. Avery, 447 F.2d 978 (4th Cir. 1971); United States v. Mensik, 440 F.2d 1232 (4th Cir. 1971). In these cases the indictments were for violations of 18 U.S.C. § 401(3). The prosecutions were commenced without any prior or precipitating action by the court.

The final inquiry is whether criminal contempt requires priming or initiating action by the court before a prosecutor or law enforcement officer may act upon the offense. We agree with the Second Circuit's conclusion that no action by the court is necessary before an indictment for criminal contempt may be handed up, United States v. Morales, 566 F.2d 402, 404 (2nd Cir. 1977):

Morales' contention that criminal contempt may not be prosecuted by indictment unless a judge first refers the matter of the alleged act of contempt to the grand jury lacks merit. Many cases have tacitly or explicitly recognized the power of grand juries to hand down indictments charging criminal contempt. E. g., United States v. DeSimone, 267 F.2d 741, 743-44 (2d Cir.), vacated as moot, 361 U.S. [827], 80 S.Ct. 74, 4 L.Ed.2d 70 (1959) (grand jury presentment); Steinert v. United States District Court, 543 F.2d 69, 70-71 (9th Cir. 1976); United States v. Mensik, 440 F.2d 1232 (4th Cir. 1971) (per curiam); United States v. Sternman, 415 F.2d 1165 (6th Cir. 1969), cert. denied, 397 U.S. 907, 90 S.Ct. 903, 25 L.Ed.2d 88 (1970); United States v. Eichhorst, 544 F.2d 1383 (7th Cir. 1976); United States v. Bukowski, 435 F.2d 1094, 1103 (7th Cir. 1970), cert. denied, 401 U.S. 911, 91 S.Ct. 874, 27 L.Ed.2d 809 (1971).

Further support for the proposition that contempt is an offense dehors any initiating action by the court is found in the holding and rationale of Pendergast v. United States, 317 U.S. 412, 63 S.Ct. 268, 87 L.Ed. 368 (1943). The Supreme Court there held that a prosecution for contempt was barred by the statute of limitations prohibiting the commencement of prosecutions more than three years after the commission of "any offense." The defendants in Pendergast perpetrated a fraud on the court, punishable as criminal contempt, during a period ending in February, 1936. The court subsequently learned of the fraud and in May, 1940, referred the matter to the prosecutor for the filing of charges. Pertinent to our instant inquiry is the court's holding that the period of limitations began to run when the acts occurred and not when the court later initiated action. The offense had occurred at the time of the contumacious act. Were it mandatory that a court act before the prosecutor could proceed, it is entirely conceivable, under Pendergast, that the statute of limitations could fully accrue before the contemnor is subject to charge and arrest. We lend no support to that anomaly.

The panel noted a decision by the Fourth Circuit that it found of little aid, United States v. Avery, 447 F.2d 978 (4th Cir. 1971) (per curiam), cert. denied, 405 U.S. 930, 92 S.Ct. 984, 30 L.Ed.2d 804 (1972). In Avery the defendant was indicted under 18 U.S.C. § 401 for unauthorized travel outside the bond restricted area. Avery had been ordered to remain in the Eastern District of Virginia but traveled to Jamaica. He was arrested upon returning to Miami. There was no prior action by the court. His conviction was confirmed by the Fourth Circuit and certiorari was denied. We find this case factually and legally indistinguishable and of precedential value.

We agree with the panel that 18 U.S.C. § 401(3) gives power only to courts, not DEA agents, to punish contumacious acts. We also agree that violations of bond conditions are punishable only by the courts. We further agree that 18 U.S.C. § 3150 imposes criminal sanctions only on willful failures to appear. However, 18 U.S.C. § 401(3) provides punishment for the violation of any lawful court order, including orders entered pursuant to 18 U.S.C. § 3146(a)(2) restricting travel. We therefore disagree with the panel's conclusion that a DEA agent does not have statutory authority under 21 U.S.C. § 878(3) to make a warrantless arrest for a violation of 18 U.S.C. § 401(3) committed in his presence.

We conclude that the willful breach of an order of court restricting travel, entered as a condition of release pending appeal, constitutes criminal contempt under 18 U.S.C. § 401(3). Such a violation is an "offense against the United States" as that term is used in 21 U.S.C. § 878(3). When agent Markonni, possessed of the knowledge that Williams was prohibited from traveling outside of Ohio, saw Williams deplane in Atlanta from a nonstop flight from Los Angeles, an offense against the United States was committed in his presence. Upon confirmation of Williams' identity, agent Markonni was fully empowered to make a valid arrest by 21 U.S.C. § 878(3).

Miranda

The panel raised sua sponte the question whether Williams' statements to Markonni should have been suppressed for Markonni's failure to give the warnings mandated by Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966). See footnote 12, 594 F.2d at 92. Miranda is not applicable to this factual situation. Other than confirmation of Williams' identity, no information elicited in the questioning of Williams was material to the determination that an offense against the United States was being committed in Markonni's presence. It was only necessary that Markonni know of the existence of the travel restrictions and see Williams in Atlanta to perceive the offense and act properly thereon. The questions about permission to travel and destination could only elicit neutral or exculpatory responses. Williams might have said and have been able to show that she had permission to travel. That answer would have negated what otherwise was an apparent criminal act. The questions and answers did not change the basic factual situation, i. e., the observation of Williams traveling outside of Ohio by a law enforcement official who was aware of a court order requiring that she stay in Ohio.

We find that the arrest by agent Markonni was legal, the search of Williams' person incidental to that arrest was proper and the heroin found in her coat pocket was lawfully seized. We further find that the search warrant was issued on the requisite showing and the heroin discovered in the luggage was the product of a lawful search and seizure.

Having reached the foregoing conclusion it becomes unnecessary for us to consider the applicability vel non of the exclusionary rule and we express no opinion with respect thereto. The granting of this rehearing en banc vacated the panel opinion (5th Cir.R. 17).

The decision of the district court granting the motion to suppress is REVERSED and this cause is REMANDED for further proceedings.

PART II

GEE and VANCE, Circuit Judges:

Many of the thirteen judges who join in this opinion do not disagree with that prepared by Judge Politz for a different majority of the court; several formally concur in it. It is our view, however, that the drugs suppressed as evidence by the trial judge and by our panel should not have been and that to suppress them was wrong whether or not Williams' violation of a bond condition was such a crime as warranted her arrest and the consequent search of her person that revealed their presence.

The facts material to our view of this case are so simply stated that we reiterate them for the reader's convenience. Special Agent Markonni, of the Drug Enforcement Administration, had previously arrested defendant Jo Ann Williams for running drugs. Pending her appeal from conviction of that offense, he knew that she was free on bond conditioned that she remain within the State of Ohio. While on duty at the Atlanta airport, he saw her deplane from an incoming, nonstop flight from Los Angeles. As she proceeded toward the departure gate for a flight to Kentucky on which she held a ticket, he arrested her for "bail jumping." A search pursuant to that arrest revealed that she was again running heroin.

Indicted for this second drug offense, committed while free on bail from the first, Williams moved to suppress the fruits of the search conducted pursuant to Markonni's arrest. The district court suppressed this evidence. On appeal from its ruling, a panel of our court affirmed. It reasoned that since violation of a bond condition was not a criminal offense such that a warrantless arrest could be made for it, both the arrest and the search pursuant to it were invalid. It therefore suppressed the heroin found as "fruit of the poisonous tree."

In the panel's view, Agent Markonni's reasonable belief, held in an unquestioned good faith, that he was authorized to arrest Williams cut no figure in the analysis. Judge Charles Clark, dissenting, would have refused to apply the exclusionary rule in such circumstances. We took the case en banc to decide this question.

Sitting en banc, we now hold that evidence is not to be suppressed under the exclusionary rule where it is discovered by officers in the course of actions that are taken in good faith and in the reasonable, though mistaken, belief that they are authorized. We do so because the exclusionary rule exists to deter willful or flagrant actions by police, not reasonable, good-faith ones. Where the reason for the rule ceases, its application must cease also. The costs to society of applying the rule beyond the purposes it exists to serve are simply too high — in this instance the release on the public of a recidivist drug smuggler — with few or no offsetting benefits. We are persuaded that both reason and authority support this conclusion.

The "Good-Faith Exception"

Analytically, it matters little whether reasonable, good-faith police actions be viewed simply as beyond the reach of the rule or as constituting an exception to its application. Since numerous writers and judges have employed the latter formulation, we shall do so here. One commentator defines the "exception" as follows: "when an officer acts in the good faith belief that his conduct is constitutional and where he has a reasonable basis for that belief, the exclusionary rule will not operate." Ball, Good Faith and the Fourth Amendment: The "Reasonable" Exception to the Exclusionary Rule, 69 J.Crim.L. Criminology 635, 635 (1978).

In fourth amendment cases, most good faith violations concern the failure to meet the requirement of probable cause. Two basic types of violation are possible. First, an officer may make a judgmental error concerning the existence of facts sufficient to constitute probable cause. Such cases may be characterized as examples of "good faith mistake." Second, an officer may rely upon a statute which is later ruled unconstitutional, a warrant which is later invalidated, or a court precedent which is later overruled. In each of these cases, the officer may be deemed to have committed a "technical violation."

Id. at 638-39 (emphasis added and footnotes omitted). The Supreme Court and this circuit have all but explicitly adopted the technical-violation facet of the good-faith exception, and each has rendered several decisions that implicitly, at least, support the good-faith mistake facet; we discuss these opinions in detail below. Many writers have advocated the exception, among them Professor Charles Alan Wright, no minor authority on criminal procedure, who proposes modifying the rule so that "the criminal is to go free if the constable has flouted the fourth amendment but not if he has made an honest blunder." Judge Henry Friendly has suggested limiting suppression to "the fruit of activity intentionally or flagrantly illegal."

At least "four current members of the United States Supreme Court have urged the adoption of a good faith exception to the exclusionary rule." Ball, supra at 635. E. g., Stone v. Powell, 428 U.S. 465, 538, 96 S.Ct. 3037, 3073, 49 L.Ed.2d 1067 (1976) (White, J., dissenting); Brown v. Illinois, 422 U.S. 590, 610-12, 95 S.Ct. 2254, 2265-66, 45 L.Ed.2d 416 (1975) (Powell, J., concurring). The Supreme Court itself, in a long series of recent decisions, has restricted the application of the rule so that it is not now — if it ever was — coextensive with the fourth amendment. E. g., Michigan v. DeFillippo, 443 U.S. 31, 99 S.Ct. 2627, 61 L.Ed.2d 343 (1979); United States v. Caceres, 440 U.S. 741, 99 S.Ct. 1465, 59 L.Ed.2d 733 (1979); Rakas v. Illinois, 439 U.S. 128, 99 S.Ct. 421, 58 L.Ed.2d 387 (1978); United States v. Ceccolini, 435 U.S. 268, 98 S.Ct. 1054, 55 L.Ed.2d 268 (1978); Stone v. Powell, supra; United States v. Janis, 428 U.S. 433, 96 S.Ct. 3021, 49 L.Ed.2d 1046 (1976); United States v. Peltier, 422 U.S. 531, 95 S.Ct. 2313, 45 L.Ed.2d 374 (1975); Michigan v. Tucker, 417 U.S. 433, 94 S.Ct. 2357, 41 L.Ed.2d 182 (1974); United States v. Calandra, 414 U.S. 338, 94 S.Ct. 613, 38 L.Ed.2d 561 (1974); Harris v. New York, 401 U.S. 222, 91 S.Ct. 643, 28 L.Ed.2d 1 (1971). We think that reason plainly demands explicit recognition of a reasonable good-faith exception as well.

Justification for the Good-Faith Exception

The exclusionary rule, it is now well settled, is not itself a requirement of the Constitution. E. g., Stone v. Powell, supra, 428 U.S. at 482, 96 S.Ct. at 3046; United States v. Calandra, supra 414 U.S. at 348, 94 S.Ct. at 620. Rather, it is a judge-made rule crafted to enforce constitutional requirements, justified in the illegal search context only by its deterrence of future police misconduct. The rule's application, moreover, must be considered in light of its direct effect of preventing the "whole truth" from being told and its byproducts of freeing guilty criminals and endangering society. Consequently, the rule is not applied in those contexts where it does not effectively deter official misconduct. E.g., Stone v. Powell, 428 U.S. at 486-87, 96 S.Ct. at 3048-49; United States v. Calandra, 414 U.S. at 348, 351-52, 94 S.Ct. at 620, 621-22; United States v. Cruz, 581 F.2d 535, 538 n. 1 (5th Cir. 1978) (en banc). Such a context is that of technically improper police actions taken in a reasonable good faith, as is persuasively argued by Judge Clark in his dissent to the panel opinion:

No proper deterrent effect is accomplished by the suppression of the evidence in this case. Field officers are seldom trained as legal technicians. Even those who are may have mistakenly thought that Officer Markonni's arrest was proper. Since the officer whose future actions are to be affected will not realize his actions are wrongful when he is compelled to make a quick decision in an apparently valid arrest situation which complicated legal analysis may later establish to be invalid, we cannot expect him to be deterred. If today's ruling does serve as any sort of deterrent, it may have the deleterious effect of making the officer on the line overcautious to act in a situation where proper and reasonable instinct tells him that the activity he observes is criminal. If he hesitates to act lest he later be criticized for denying to the process of justice evidence of crime, we have hindered, not furthered, the interests of justice. Unless an officer knows or should know his activities transgress the bounds of law, the evidence discovered by such activity ought not be suppressed.

United States v. Williams, 594 F.2d 86, 97-98 (5th Cir. 1979). It makes no sense to speak of deterring police officers who acted in the good-faith belief that their conduct was legal by suppressing evidence derived from such actions unless we somehow wish to deter them from acting at all. The Supreme Court recognized this in Janis in admitting evidence obtained in good faith under a warrant later found defective. "[T]he officers here were clearly acting in good faith, . . . a factor that the Court has recognized reduces significantly the potential deterrent effect of exclusion. See Michigan v. Tucker, 417 U.S., at 447 [ 94 S.Ct., at 2365]; United States v. Peltier, 422 U.S., at 539 [ 95 S.Ct., at 2318]." 428 U.S., at 459 n. 35, 96 S.Ct., at 3034 n. 35. Justice White as well has noted this lack of any deterrent effect:

When law enforcement personnel have acted mistakenly, but in good faith and on reasonable grounds, and yet the evidence they have seized is later excluded, the exclusion can have no deterrent effect. The officers, if they do their duty, will act in similar fashion in similar circumstances in the future; and the only consequence of the rule as presently administered is that unimpeachable and probative evidence is kept from the trier of fact and the truth-finding function of proceedings is substantially impaired or a trial totally aborted.

Stone v. Powell, 428 U.S. at 540, 96 S.Ct. at 3073-74 (White, J., dissenting). And again, Professor Wright has pithily observed that a "police officer will not be deterred from an illegal search if he does not know that it is illegal." Wright, supra at 740.

Any slight deterrent effect of excluding fruits of good-faith arrests is even less than the small deterrence from suppressing the fruits of illegal police actions that are attenuated in effect, that are challenged in habeas corpus petitions on fourth amendment grounds, that are used in grand jury deliberations, or that are used for impeachment. Yet the Supreme Court has found that the deterrent effect of exclusion in the examples listed and others does not justify the societal harm incurred by suppressing relevant and incriminating evidence. United States v. Ceccolini, 435 U.S. 368, 98 S.Ct. 1054, 55 L.Ed.2d 268 (1978); Stone v. Powell, supra; United States v. Peltier, 422 U.S. 531, 95 S.Ct. 2313, 45 L.Ed.2d 374 (1975); Michigan v. Tucker, 417 U.S. 433, 94 S.Ct. 2357, 41 L.Ed.2d 182 (1974); United States v. Calandra, 414 U.S. 338, 94 S.Ct. 613, 38 L.Ed.2d 561 (1974); Harris v. New York, 401 U.S. 222, 91 S.Ct. 643, 28 L.Ed.2d 1 (1971). The good-faith exception that we explicitly recognize today is of a kind with these.

Support in Authority for the Technical Violation Facet of the Good-Faith Exception

The most common forms of "technical violations" made in good faith are arrests made in good-faith reliance on a statute that is later declared unconstitutional or, as here, on a reasonable interpretation of a statute that is later construed differently. Of course, the exception applies only if the police belief is both bona fide and reasonable. Suppression still results if officers allege a good-faith belief in a "law so grossly and flagrantly unconstitutional that any person of reasonable prudence would be bound to see its flaws" or in a law that violated a "controlling precedent that [it] was . . . unconstitutional." Michigan v. DeFillippo, 443 U.S. at 38, 99 S.Ct. at 2632.

In DeFillippo the Supreme Court admitted evidence seized in a good-faith arrest with probable cause (without a warrant) for violation of a law later declared unconstitutional. An officer arrested DeFillippo in good-faith reliance on such an ordinance, finding drugs in a search of DeFillippo's person made incident to the arrest. The Court ruled, in words that seem applicable to Officer Markonni's search of Williams' person and luggage:

[T]here was no controlling precedent that this ordinance was or was not constitutional, and hence the conduct observed violated a presumptively valid ordinance. A prudent officer, in the course of determining whether respondent had committed an offense under all the circumstances shown by this record, should not have been required to anticipate that a court would later hold the ordinance unconstitutional.

Id. 99 S.Ct. at 2632. This decision was rendered after the instant panel decision, so the panel did not have the benefit of the Supreme Court's disposition of this closely analogous fact situation.

In United States v. Peltier, 422 U.S. 531, 95 S.Ct. 2313, 45 L.Ed.2d 374 (1975), the Supreme Court admitted evidence seized in a good-faith border search without a warrant under a statutory construction that was subsequently held unconstitutional. Border patrol agents made a warrantless search of Peltier's automobile, in reliance on a longstanding administrative definition, continuously approved judicially, of a reasonable distance from the border for such searches as 100 miles; and Peltier was convicted on evidence seized during that border search. The Supreme Court later overturned that definition of a reasonable distance. The Court refused to exclude the challenged evidence and refused to apply that subsequent decision retroactively: "evidence obtained from a search should be suppressed only if it can be said that the law enforcement officer had knowledge, or may properly be charged with knowledge, that the search was unconstitutional under the Fourth Amendment." Id. at 542, 95 S.Ct. at 2320.

In United States v. Carden, 529 F.2d 443 (5th Cir. 1976), we sustained an arrest and search made in good faith under a statute later declared invalid. The Cardens were arrested and searched under an ordinance against loitering, and a large bag of coins found in the search was used to convict them of robbing a government building. The ordinance was subsequently found unconstitutional, but the evidence derived from the good-faith search was not excluded.

This Court has held more than once that an arrest made in good faith reliance on a statute not yet declared unconstitutional is valid regardless of the actual constitutionality of the ordinance. Hamrick v. Wainwright, 465 F.2d 940 (5 Cir. 1972); United States v. Kilgen, 445 F.2d 287 (5 Cir. 1971). See also . . . Moffett v. Wainwright, 512 F.2d 496, 502 n. 6 (5 Cir. 1975). While appellants would be entitled to attack the constitutionality of any convictions under the Anniston ordinance, "there is no bar to the use of evidence of other crimes obtained during incarceration for violation of a law which was valid when the arrest was made." 465 F.2d at 941-42.

. . . [W]e have been reluctant to, and will not in this case, also require that [police officers] forecast future judicial decisions as to the constitutionality of the statutes under which they must make arrests. There is no evidence whatsoever in the record that the arresting officers did not believe that the Anniston loitering ordinance was constitutionally valid. No judicial decision existed, or now exists so far as we know, to negate that conclusion. Under such circumstances, we must reject the Cardens' attempt to assert the unconstitutionality of the ordinance to invalidate their arrest.

Id. at 445.

In United States v. Kilgen, 445 F.2d 287 (5th Cir. 1971), this circuit admitted evidence obtained in good faith under a similar statute. Kilgen was arrested and charged in good faith with violation of a vagrancy ordinance, and he consented to the officer's opening an automobile trunk where the officer saw numerous postage stamps and money orders. Kilgen confessed to the crime of stealing these things. We sustained admission of the confession because the police had arrested Kilgen in good faith, and hence exclusion would not deter any official misconduct, although the ordinance was later overturned.

But overturning a [vagrancy] conviction due to an invalid statute does not automatically render the previous arrest and detention illegal absent some showing that police officials lacked a good-faith belief in the validity of the statute. . . . There is no hint of any abusive police conduct in effecting the arrest or in obtaining the evidence used at the trial for another crime. . . . In short, this is a clear case of police officers who, with the utmost regard for the rights of the defendant, carried out their sworn duty to make an arrest and obtain evidence under the law as it then existed. No legitimate interest would be served by excluding the confession to the separate crime of stealing postage stamps because we now find the vagrancy ordinance invalid.

Id. at 289. See also United States v. Warren, 578 F.2d 1058, 1077 n. 17 (5th Cir. 1978) (en banc), rehearing en banc granted, 589 F.2d 254 (5th Cir. 1979) ("The validity of an arrest depends upon the reasonableness of the officers' actions at the time of the arrest and not upon what a court may glean from a statute three and a half years later. This rule is well established even where the statute under which the arrest was made is after declared unconstitutional.").

Support in Authority for the Good-Faith Mistake Facet of the Exclusionary Rule

If Officer Markonni was mistaken in his belief that Williams' violation of her bond conditions authorized him to arrest her, as the trial court and our panel both held he was, his mistake was one made in a manifest good faith. Much authority also supports this facet of the exception that, we reiterate, requires a reasonable belief, as well as a good-faith belief, on the part of law enforcement officials.

In United States v. Janis, 428 U.S. 433, 96 S.Ct. 3021, 49 L.Ed.2d 1046 (1976), the Supreme Court refused to exclude from a federal tax proceeding evidence that had been obtained by state police in good-faith reliance on a search warrant later found defective. State police had seized wagering records and cash from Janis under a search warrant issued on allegations of bookmaking. A state court, finding the officer's affidavit that supported the warrant defective, suppressed that evidence. The Internal Revenue Service assessed Janis for excise taxes on wagering and levied on the seized cash. Janis filed a refund suit in district court and moved to suppress that evidence. The Supreme Court stated the issue and then resolved it as follows: "Is evidence seized by a state criminal law enforcement officer in good faith, but nonetheless unconstitutionally, inadmissible in a civil proceeding by or against the United States?" Id. at 434, 96 S.Ct. at 3023 (emphasis added).

[W]e conclude that exclusion from federal civil proceedings of evidence unlawfully seized by a state criminal enforcement officer has not been shown to have a sufficient likelihood of deterring the conduct of the state police so that it outweighs the societal costs imposed by the exclusion. This Court, therefore, is not justified in so extending the exclusionary rule.

Id. at 454, 96 S.Ct. at 3032 (footnote omitted).

In Michigan v. Tucker, 417 U.S. 433, 94 S.Ct. 2357, 41 L.Ed.2d 182 (1974), the Court declined to exclude the testimony of a witness located as the result of statements made by the accused during police interrogation administered "in complete good faith" but without proper Miranda warnings. The police questioned Tucker after his arrest for rape without giving full Miranda warning, and he voluntarily gave the alibi that he had been with Henderson. Henderson subsequently testified against Tucker, and Tucker moved to suppress his incriminatory statements on the ground that his identity was obtained in the improper interrogation. The Supreme Court admitted Henderson's testimony.

The deterrent purpose of the exclusionary rule necessarily assumes that the police have engaged in willful, or at the very least negligent, conduct which has deprived the defendant of some right. By refusing to admit evidence gained as a result of such conduct, the courts hope to instill in those particular investigating officers, or in their future counterparts, a greater degree of care toward the rights of an accused. Where the official action was pursued in complete good faith, however, the deterrence rationale loses much of its force.

Id. at 447, 94 S.Ct. at 2365.

In United States v. Hill, 500 F.2d 315, 322 (5th Cir. 1974), cert. denied, 420 U.S. 931, 95 S.Ct. 1135, 43 L.Ed.2d 404 (1975), this circuit admitted evidence obtained in a search although the warrant was technically improper. The search warrant was issued upon an insufficient affidavit of a law enforcement agent, and the subsequent search of Hill's residence yielded heroin. We admitted the heroin and affirmed Hill's conviction because we allowed the affidavit to be bolstered by the sworn testimony of the agent before the magistrate.

[T]his situation furnishes no occasion to apply the exclusionary rule to bar the evidence of Hill's criminality that was obtained in executing the warrant. Phillips acted properly in going to the magistrate and seeking a warrant. Magistrate Sear acted properly in calling for additional information to demonstrate credibility. Thus, the only error attributable to the procedure they followed is a technical one that would in no way serve the deterrent purposes of the rule.

Id. at 322 (alternative ground).

In United States v. Wolffs, 594 F.2d 77 (5th Cir. 1979), we refused to exclude evidence obtained through improper collaboration of federal and state agents. Pugh, a member of the United States Army, arranged a marijuana purchase from Wolffs at the suggestion of a county sheriff. An Army investigator and some sheriff's office personnel arrested Wolffs and his accomplices and seized the marijuana, thus violating the Posse Comitatus Act, 18 U.S.C. § 1385. The panel, recognizing the agents' good faith in that this was an isolated act, refused to apply the exclusionary rule.

[A]ssuming without deciding that there was a violation, application of an exclusionary rule is not warranted. If this Court should be confronted in the future with widespread and repeated violations of the Posse Comitatus Act an exclusionary rule can be fashioned at that time.

594 F.2d at 85. See also Leary v. United States, 544 F.2d 1266, 1270-71 (5th Cir. 1977).

The recent decision of the Supreme Court in Ybarra v. Illinois, 444 U.S. 85, 96, n. 11, 100 S.Ct. 338, 345 n. 11, 62 L.Ed.2d 238 (1979), does not militate against the goodfaith exception. The Court there held that a search of Ybarra and other patrons of a bar violated the fourth amendment because it was not authorized by a warrant to search the bartender and was not justified by probable cause to believe that Ybarra possessed heroin or a reasonable belief to anticipate that he was armed. Exclusion of evidence seized without any probable cause is an entirely different question from suppression of evidence seized upon a goodfaith and reasonable belief in the existence of probable cause. The Supreme Court in DeFillippo, supra, while refusing to exclude evidence seized in good-faith reliance on a subsequently invalidated statute, noted that "the exclusionary rule requires suppression of evidence obtained in searches carried out pursuant to statutes . . . which purported to authorize the searches in question without probable cause." 99 S.Ct. at 2633. And the Court in Ybarra distinguished DeFillippo on precisely this basis when it emphasized that the "statute purports instead to authorize the police in some circumstances to make searches and seizures without probable cause." 444 U.S. 96 n. 11, 100 S.Ct. 345 n. 11.

Application of the Good-Faith Exception to This Case

Officer Markonni recognized with certainty that Williams was in violation of her bail limitations and that she was arriving from the very city from which she had obtained the heroin that caused her first conviction, rendered on a guilty plea. He acted in a good-faith belief that Williams' conduct violated 18 U.S.C. § 3146. This circuit at the time of the arrest had not ruled that a person violating bail requirements, but not a court appearance date, could or could not be arrested on that basis, and the only circuit that had inferentially done so had sustained the conviction. Officer Markonni also acted under a reasonable, whether or not mistaken, belief and should not be charged with knowledge that a future panel decision would construe section 3146 to apply only to bond jumping that involved missing a court appearance. This case presents the questions both of a "goodfaith mistake," an action under a reasonable factual error about an element of the crime defined in section 3146, and a goodfaith "technical violation," an action under a reasonable interpretation of the arrest power under section 3146 that was subsequently reconstrued by our panel. Williams is not on trial for bail jumping. Williams is on trial for possession of a large quantity of heroin. A good-faith mistake about the legal intricacies of bail jumping would not require exclusion of that heroin found in an incidental search.

Conclusion

Henceforth in this circuit, when evidence is sought to be excluded because of police conduct leading to its discovery, it will be open to the proponent of the evidence to urge that the conduct in question, if mistaken or unauthorized, was yet taken in a reasonable, good-faith belief that it was proper. If the court so finds, it shall not apply the exclusionary rule to the evidence. Neither Markonni's good faith nor its reasonableness are questioned here, and a proper allocation of the burden of proof on this issue is therefore not squarely presented by the facts of this case. We therefore leave that matter to another day, going no further than to delineate the "exception" itself explicitly and to recognize that where the proponent establishes it, the evidence should be received if otherwise admissible.

Predictably, it will be argued that today's decision undercuts the fourth amendment. Not so; it concerns only the exclusionary rule, one device — but not the sole one — for enforcing the amendment, and a device that is already far from co-extensive with the amendment itself. As for the exclusionary rule, insofar as we restrict its application, we do so only to conform that to its underlying purpose: to deter unreasonable or bad-faith police conduct.

Where the reason for a rule ceases, the rule should also cease — a familiar maxim carrying special force here. For here the cost of applying the rule is one paid in coin minted from the very core of our factfinding process, the cost of holding trials at which the truth is deliberately and knowingly suppressed and witnesses, in contravention of their oaths, are forbidden to tell the whole truth and censured if they do. This is a high price indeed and one that ought never be paid where, in reason, no deterrence is called for and none can in fact be had. Such a continued wooden application of the rule beyond its proper ambit to situations that its purposes cannot serve bids fair to destroy the rule entirely in the long run. For the reasons we have stated, in addition to and independent of those given in Judge Politz' opinion, the decision of the district court excluding Williams' heroin and the panel opinion affirming it are

REVERSED.
