When the detectives are using the police radio, they aren't using police codes.
Doris and Ruthie are in a fist fight/cat fight and there are no marks on either of them. The sounds during the fight scene imply a violent fight.
When one of the goons that gets shot in the leg, his wound changes places on the same leg, then switches legs, then switches back.
When Leroy is shot, the blood stain is away from the body and there is no visible place where he could have been bleeding from.
Ruthie fell out of a moving vehicle backwards but landed on her stomach, face down.
When Dick gets shot his shoes are magically removed and away from the body, plus no bullet wound.
When Ruthie gets shot, her wound is not a bullet wound (more like a wound from a stabbing) and there is no blood coming from the fresh wound (it wouldn't have stopped bleeding that fast).
