Continuity mistake: Just as Gage and DeSoto walk into Rampart's staff lounge, while discussing practical jokes, DeSoto is holding the handy-talkie in his right hand, but in the next shot the handy-talkie has vanished.
Continuity mistake: After Squad 51 is dispatched to "possible heart case" when Roy and Johnny walk into the house, we can see in the hallway and there's a bureau against the wall, but when they leave that bureau is gone and now there's a painting on the wall which we should have seen in the earlier shot, but it wasn't there.
