Other mistake: Athena Carter (Sgt. Grant in her younger years) takes Officer McCluskey to the armored truck. She has her finger not on the trigger, but still fires off a shot (without recoil). Muzzle flash is a single frame. (00:21:14)
Other mistake: Athena goes to her patrol car to turn on the lights so the chopper can see her and the victim, but as she approaches her cruiser, the lights are reflecting on the ground already, even though they weren't activated yet.
Other mistake: The woodchipper is shown cutting wood, but is squeaky clean when the golfer sticks his hand in it to get the ball out.
