In Giglio v. U.S., exculpatory evidence includes information that could question the credibility of a prosecution witness, including officers.

• A. Exculpatory evidence pertains only to physical evidence
• B. Exculpatory evidence includes witness credibility information, including officers
• C. Exculpatory evidence is never disclosed
• D. Exculpatory evidence relates only to the defense

Answer: (B)

Exculpatory evidence includes any information that could be used to undermine a witness’s credibility, not just physical items. Giglio v. United States requires prosecutors to disclose impeachment information about any witness, including officers who testify for the government. This ensures the defense can assess the reliability of the testimony and prevents unfair advantage from undisclosed credibility issues, such as deals, biases, or prior misconduct. The other statements misstate the scope: exculpatory evidence is not limited to physical evidence, it is not true that such evidence is never disclosed, and it does not pertain only to the defense.
