When Abby (Julie Benz) is standing in front of the police roadblock attempting to stop the truck, the cops behind her are all in position with guns aimed. Cut to the truck driver who speeds up and back to the wide shot of the roadblock where you can see the cops running to get out of the way. Cut back to the truck and back again to Abby, the cops are back in their original positions with guns aimed.
During the police chase of the semi, the police helicopter cannot continue to fly over the semi and jam the enemy cell phone because of restricted air space. If this was true then the news helicopter also would have to leave and there would be no coverage of the children being moved from the back of the car. The enemy would not have seen it and have sped up.
