What's wrong with it? He's not making the usual "tiger-proof rock" argument used to refer to the TSA, after all. The TSA doesn't, as a rule, catch people who were actually planning to cause trouble. They either catch people who didn't know/care how much toothpaste they were allowed to smuggle onboard, or they catch idiots who forgot they were carrying a .50 caliber Desert Eagle in their shaving kit. This is a different argument altogether.
