In a scene where the robbers are climbing into the police station back yard, the ladder they are using does not reach the top of the wall. However, when they drop down on the other side, the top of the ladder is at least 2 feet above the wall. Similarly when George first spies the ladder against the girl's window, it reaches above the window ledge, but when the young man climbs it when the couple are eloping, it does not reach to the window.
