The only thing that shocks me is why this doesn't happen in Las Vegas more often. It's the perfect storm for terrorist attacks. Huge crowds, can carry weapons in and out casinos without detection and any shooting or act of terrorism there brings worldwide, massive publicity. After 9/11 they were screening vehicles going in parking garages. You should be forced to pass through metal detectors entering casinos. They do it at the nightclubs there. How about using it on anyone who enters a casino.
