Hammer Down - S6-E7
Visible crew/equipment: Season 6, episode 7 "Hammer Down": Just after Mac and Ray have finished briefing the other officers as they are about to begin a chase, there is an actor's red T-mark on the floor, visible just as the officers begin to walk towards the scene.
Chosen answer: Probably to broaden the scope of the show's plot and give the audience a chance to see the characters in a different setting, People act differently at home from the way they do at their workplace. By the ninth season, the characters would have become overly familiar and predictable. It gives the writers a chance to do something different with them.
