The Fallen - S14-E19
Factual error: DB Russell gives Mark Roberts a bottle of water to hold. In the blood he leaves his fingerprint on the bottle. Stokes is watching with another policeman the CCTV footage from the interview room. Stokes then says grab a screen shot of the water bottle. They zoom in and low and behold they get a totally clear fingerprint. No way to get that much clarity from a CCTV camera. (00:17:00)
