As I was leaving the courthouse today I watched a commotion at the metal detector. A guy tried to back through it after the cadets asked him what was in his pockets. They pursued, cuffed and searched him. He had a bottle of pills, Tylenol 3 and probably some other stuff, for which he could not produce a prescription. One cadet asked him if he was under orders not to possess such things, and he put his head in his hands and started to cry.
I felt bad for the guy. He had come to the courthouse just to pay a fine and he didn't think to take the controlled substances (and relatively benign controlled substances, at that) out of his pocket first. The cadet was impassive.
