If a witness is untruthful or mistaken, their account must be memorialized in written records and what government obligation applies?

• A. The government must disclose exculpatory materials that may impeach testimony.
• B. The government must rewrite it.
• C. The government must destroy the account.
• D. The government must withhold it from defense.

Answer: (A)

Disclosure of impeachment materials is the key idea. When a witness’s account is memorialized in written form, the government must disclose any exculpatory materials that may impeach testimony, per Brady v. Maryland and related discovery rules. This obligation ensures the defense can assess credibility and pursue a fair trial by having access to evidence that could undermine or contradict the witness’s statements. Rewriting, destroying, or withholding the written record would violate duties to preserve evidence and disclose favorable information, so those options don’t fit.
