When Tony is being stalked by Cole, Tony stops at an ATM. We see Cole's truck pass Tony's empty car, and there are no vehicles in the background. A few seconds later, we see the same shot of the empty car, but now, instead of being in front of Tony's car, where it should be, Cole's truck is parked in a parking lot in the background of the shot.
In the garage scene, Josie shoots Cole several times. In one shot, the pistol slide locks back, indicating an empty magazine. In the next shot, she shoots him again while he is on the ground.
During the final confrontation in the garage, her grip on the gun keeps changing, with several angles showing a finger on the top of the slide, which would cause injury if fired. Then, she proceeds to manually cock the hammer, but since this is a semi-automatic and has already been fired, the hammer would've already been cocked.
When Josie and Cole are struggling in the tunnel at the park, Cole wrestles away Josie's revolver and fires it 3 times at some would-be rescuers. Josie gets away and runs to the end of the tunnel. Cole fires the gun at her another 7 times. A total of 10 shots from a revolver holding 6 bullets.
