OK, on the part where the Clarks are in New York, they get in a cab. The cab driver repeatedly tells them to exit the car. They say, "No" standing up for their rights and end up with some burglers. As they pass a park, they get the gun away from the burglars, and they slow down to let them out. The Clarks jump out of the cab and as soon as they do the door swings closed as if someone closed it behind them, but if you remember, nobody was in the back seat with them and the only other two people were in the front seat where the back door isn't able to be reached.
