Continuity mistake: When Nick is staring intently at the doctors lapel area, the camera zooms in and we see some lint on the doctors left lapel. When Nick asks Catherine to get the tape on it, Catherine approaches the suspect and she starts to put the tape on the left lapel, but when the camera zooms in for a close-up of her getting the lint, the tape is being applied to the RIGHT lapel.
Continuity mistake: Nick is eating a hot dog when he's handed a warrant. Depending on the camera angle, he goes from taking a bite out of the hot dog to holding the hot dog in one hand and the warrant in the other simply with camera angle changes.
