Grievous police errors that could cost an officer their life were frequently committed by Malloy and Reed, whereby this supposed seasoned officers regularly turned their backs on perps, or allowed them to fetch and/or brandish guns without showing much of any care as to their own safety.
Whenever there is an insert of either the radio, the "hot sheet" (list of stolen cars), or when Reed is jotting down information on the pad, the visuals almost never match the continuity of the scene. Example: It can be daytime in the scene, but when the insert of the radio or the hot sheet is shown, they appear, due to the lighting, that the inserts are from nighttime. Also, the same insert of Reed writing on the pad is used whenever he writes info down. As with the errors with the radio not matching the scene, there are times when Reed is wearing the short-sleeve uniform, yet when he's writing info down, we see the cuff of a long-sleeve shirt.
Many times when the camera shot is of the radio and siren box (when Reed or Malloy talks on the two-way radio), they are clearly talking into a Motorola microphone that is plugged into the siren box instead of the radio. This microphone is used when the public address (P.A.) function of the siren box is used to hail people in-front of the vehicle. Also you can see that there is nothing plugged into the actual radio microphone socket which is located on the lower left side of the radio.
In all episodes throughout the series, during any interior scenes showing the captain's office, which is depicted as having a door and windows facing the hallway and a wall with a window looking into the adjoining office, there is never any glass in either the doors or windows.
