Factual error: After the cops respond to the domestic disturbance (son hitting mom), we see the male officer get in the back with the boy to show him the crime scene photos and he shuts the door after getting in. Police cars are designed so that the back doors must be opened from outside, however, he exited the car with no help.
Audio problem: When the cops get into the gun shop to buy some weapons you see a police officer on the left loading a M4 (or checking something) but you never hear the sound of this action.
Continuity mistake: In the scene where Larry Phillips and Emil Matasareanu walk back inside the bank, Emil Matasareanu pulls his ski mask up off his face. In the next shot the mask is still over his face and is off again in the next shot. (00:52:10)
