This is private property, you have no juristiction here!
Therefore me and my friends are within our rights to shoot cops!
That was the only part I didn't like about the movie. Seemed like a stretch that those security guys would be so quick to try and ambush the cops. I don't care what part of the country you're in, an act like that brings the heat like no other. They would've never gotten away with it and they had to know it.
