Plot hole: It's a good thing Jake left the Corps....here he is lying in the bed of a pickup with a full-auto weapon, and he can't take out the radiator of a vehicle 20 feet back, with not one, not two, but 3 clips of ammunition. A few rounds through the radiator, coolant is gone, and the motor seizes.
Continuity mistake: Jake and Olivia leave their broken car near the woods. The windshield wipers are in the upper position and the driver's door is opened. As the bad guys arrive, the windshield wipers are in the lower position and the door is closed. Then they come close to the car, the windshield wipers are a bit higher and the door is wide open.
Continuity mistake: During the assault on the police station, detective Redman shoots at the bad guys from his office door. The bad guys shoot at him too and we see bullet holes appearing on the corner of the door labelled "S10". A few seconds later Redman shoots again, then protects himself in his office, and the corner of the door is undamaged.
