Evidence of the conviction of a witness for a crime not involving dishonesty or false statement shall be inadmissible for the purpose of impairing his or her credibility. If the witness be the accused in a criminal proceeding, no evidence of his or her conviction of a crime shall be admissible for the sole purpose of impairing his or her credibility unless the witness has first introduced evidence admissible solely for the purpose of supporting his or her credibility.
