Comment
Fed. R. Evid. 608 (A Witness’s Character for Truthfulness or Untruthfulness) and 609 (Impeachment By Evidence of a Criminal Conviction) place restrictions on the use of instances of past conduct and convictions to impeach a witness, and Fed. R. Evid. 105 (Limiting Evidence That Is Not Admissible Against Other Parties or for Other Purposes) gives a defendant the right to request a limiting instruction explaining that the use of this evidence is limited to credibility of the witness.
