Or you follow the Isreali model. They don't have to run a gaunlet to go to a mall. They have good security, but it is non-intrusive.

Let me share one of my favorite stupid criminal stories. Man gets off a plane in Isreal. He is broke, so he decides to rob a store. Toy pistol vs. customers with real Uzis. He survived, got life for his stupidity. The customers shrugged it off, they were just doing thier part as citizens.

Sounds like a better plan to me.
