The credibility of a witness may be attacked or supported by evidence in the form of opinion or reputation, but subject to these limitations:
(1) the evidence may refer only to character for truthfulness or untruthfulness, and
(2) evidence of truthful character is admissible only after the character of the witness for truthfulness has been attacked by opinion or reputation evidence or otherwise.
Specific instances of the conduct of the witness, for the purpose of attacking or supporting the witness' character for truthfulness, other than conviction of crime as provided in Rule 609, may not be proved by extrinsic evidence. They may, however, in the discretion of the court, if probative of truthfulness or untruthfulness, be inquired into on cross-examination of the witness (1) concerning the witness' character for truthfulness or untruthfulness, or (2) concerning the character for truthfulness or untruthfulness of another witness as to which character the witness being cross-examined has testified.
The prosecutor in a criminal case may not cross-examine the accused or defense witness under subdivision (b) unless (1) the prosecutor has given the defense notice of intent to cross-examine pursuant to the rule; (2) the prosecutor is able to provide the trial court with sufficient evidentiary support justifying the cross-examination; and (3) the prosecutor establishes that the probative value of the cross-examination outweighs its potential for creating unfair prejudice to the accused.
The giving of testimony, whether by an accused or by any other witness, does not operate as a waiver of the accused's or witness' privilege against self-incrimination when examined with respect to matters which relate only to credibility.
