Rule 608. Evidence of Character and Conduct of


(a) Opinion and Reputation Evidence of Character. 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.

(b) Specific Instances of Conduct. Specific instances of the conduct of a witness, for the purpose of attacking or supporting the witnessí 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 witnessís 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 giving of testimony, whether by an accused or by any other witness, does not operate as a waiver for the accusedís or the witnessís privilege against self-incrimination when examined with respect to matters that relate only to character for truthfulness.
