Factual error: The bounty hunter, Frankie's, car has a Florida license plate on the front of the car. Florida only issues one license plate for vehicles, and it goes on the rear of the vehicle. (00:15:15)

Factual error: John fires a grenade launcher at a street gang hangout bar front window. Aside from the fact that such a round would hardly have been slowed enough to just roll down the bar, the round is shown complete with cartridge case, which would remain behind in the launcher/gun - it doesn't fly with the round.
