As Mike Bennett and Chuck Wheeler are turning the armored car around after hearing the report on the police radio, the shadows on the mountain road change.
During the shootout Chuck is using his rifle with the silencer but on the soundtrack you can hear the gun firing.
When Vi Victor is arrested at the end, the police place her in the first police car in front of the garage which was involved in the shoot out and was the car in which the policeman who was shot came from. The shot policeman was lying right in front of the door and would have blocked access to the car. In any event, that car would not have been used or moved until after the crime scene technicians had completed their analysis.
After the shoot out, the police enter the garage and arrest Vi who is in the garage. They would have no idea what her involvement was or if she was involved at all with the crime. Her presence there alone wouldn't make her guilty of anything.
Just past 11 minutes Vi Victor walks past a mirror; the shadow of the boom mic is briefly visible in the top of the mirror.
