I went to the game and witnessed this. Going into the stadium, they are looking in purses and bags. A guy get selected for a "random wand search" and empties all but his right-front pocket. The wand triggers on this. The security person asks him to remove the metal in his pocket. He refuses. The security person says then "I'll have to assume you are armed." The guy and his daughter say "we'll just leave then". They leave. Later, I see the guy in the stadium, and sure enough I take a good look at his right-front pocket and can (barely) make out the print of a pistol. The "security" show must go on.
