Revealing mistake: After Frank shoots Kevin and Kevin's SUV hits the curb, the background/scenery changes as well as the position of Frank's car. Frank initially pulls along the curb (behind the SUV) with his car at about a 30° angle. The next time Frank's car is shown, it is almost perpendicular to the curb and the Food Mart. When Rupple and Frank have their guns aimed, they would be aiming inside the Mart, not toward Kevin. Objects in the background also change (e.g, fire hydrant, telephone pole appear). (00:16:48)
Revealing mistake: When Poole arrives at the accident scene, both vehicles involved are in different positions. Kevin's SUV is partly in front of the Food Mart. Frank Lyga's car is about twice as far away from the SUV, the front is angled outward, and it isn't even close to the curb. Also, there are parking spaces to the right of the Mart, but not the handicapped parking that was there earlier. (00:19:26)
