Land of Make Believe

AITOOW notices that guards in movies never seem to be on "jumpy" although they are in a foreign country or a prison surrounded by danger? They just let any little suspicious irregularity slide. They are also a subset of movie characters that never fire below the waist. All you have to do is hit the ground and they fire right over you. I won't even get into how wooden furniture or sheet rock seems to be bullet proof.
