Corrected entry: In the scene where the CIA agent shoots the DEA boss (Denzel's boss) in his house he shoots him once in the chest and he falls to the ground. After they finish talking with Denzel the CIA boss shoots the DEA guy three more times in the chest with Denzel's gun (making four shots total), but when they show his body he only has three bullet wounds. All shots were to the chest as the gun angles show.

Revealing mistake: During the big shoot-out at the end, the close-up of the brown Ford pickup is flipped side to side. Check out the F150 logo on the fender, which appears as a mirror image.
Bank Manager: I'm innocent.
Earl: Nobody's innocent, friend. There just the guilty, the ignorant, and the unlucky.
Correction: The final shot hit the side and wouldn't be visible when they show his body.
