Visible crew/equipment: S01E13 - "Game, Set. Murder?". When Shawn and Gus runs out of the crime scene apartment, heading for the restaurant across the street, you can see the camera and a crew member sitting on a chair reflected in the mirror behind Gus.
Continuity mistake: As Shawn and Gus enter the office where Juliet, Carlton, and Chief Vic are sitting at the table, Carlton puts the case file he is holding on the table. Two shots later he is holding the file again, and for the next few shots his hands keep changing position without time for him to move them.
