When the suspect in the garage is apprehended and is ordered by Reed to kneel, he does so, right on the handgun he had just been ordered to drop. In the next shot from a different angle, the handgun is several inches from the suspect and Reed is seen kicking it away from him.
When Reed and Malloy find Officer Jerry Woods at a domestic call, Malloy is talking to Woods on the front steps. Woods has his arms crossed. When the scene changes to them walking away from the door, the position of one of his hands goes from being tucked under his arm to being on top of his arm.
When Malloy exits The Leaning Tower of Pizza, one can see the black cables of the film equipment on the ground leading into the location.
The cameraman is reflected in Malloy's mirror when driving to the meeting place.
At about 18 minutes in, as Pete backs out of the parking lot, a bar or cable of some sort (painted black & white) is clearly seen attached to left fender and driver's door.
When Reed is posing as a pizza delivery man, he is at the front door holding the pizza box vertically, instead of horizontally.
When Malloy and Reed arrive at the address of the domestic call to check on Woods and his partner's well- being, Woods steps outside and chats with Malloy, while the woman goes back inside and closes the door. Woods, being a seasoned officer, should know better than to allow his partner to be left inside alone, especially on a domestic call which are known to be the most dangerous calls an officer can respond to.
