Do your homework and make sure that there isn't a cop convention in town. I love this story. Totally the dumbest person I have read about yet.

"A retired police chief said he was robbed by "probably the dumbest criminal in Pennsylvania," at a police officers' convention on Friday morning. John Comparetto said as he came out of a stall in the men's room, a man pointed a gun in his face and demanded money. There were 300 narcotics officers from Pennsylvania and Ohio at the gathering."
