What is the difference between credibility impeachment under 608(a) and conviction impeachment under 609?

• A. 608(a) concerns character for truthfulness; 609 concerns prior convictions to attack credibility.
• B. 608(a) concerns prior convictions; 609 concerns character for truthfulness.
• C. 608(a) concerns expert testimony; 609 concerns lay testimony.
• D. 608(a) concerns chain of custody; 609 concerns authentication.

Answer: (A)

The difference rests in what each rule uses to attack credibility. Impeaching a witness’s credibility under this rule focuses on the witness’s character for truthfulness, typically through reputation or opinion about whether the witness is honest. It’s about the trait of honesty itself, not about a specific crime. Evidence of a witness’s truthfulness can be discussed through their general character, and specific instances of conduct can be explored on cross-examination under a separate provision, rather than as a stand-alone admission. Impeaching credibility using prior criminal convictions, on the other hand, relies on actual past crimes to suggest untrustworthiness. This uses concrete, recorded conduct rather than a broad character assessment, and it’s governed by particular rules about what kinds of offenses can be admitted and when, including how old the conviction is and other balancing considerations. So the correct distinction is that the first deals with character for truthfulness, while the second deals with prior convictions used to attack credibility. The other options mix in topics like expert versus lay testimony or chain of custody and authentication, which aren’t about impeachment of credibility.
