Flashcards Studio

Defendant is charged with robbing a pharmacy. Cashier testifies that she personally saw Defendant point a silver handgun and leave through the south door. The government also calls Detective, who did not witness the robbery but reviewed the pharmacy's surveillance video. Detective proposes to testify, "The video shows Defendant taking cash from register two and leaving through the south door." The government offers three still screenshots exported from the video system but not the full video file.
Defendant objects that the best evidence rule bars both Cashier's testimony and Detective's testimony unless the government produces the complete video. The government responds that the screenshots are enough and that the video system overwrites full files after 30 days unless saved.
How should the court rule? Discuss personal knowledge, proof of recording contents, screenshots or exports as originals or duplicates, and any separate fairness or completeness concerns.
