Oh, I have so got to hear the rest of this story.
I can't see a crook reaching over a stall door to grab a jacket unless he knew it was there. Maybe followed the cop or something and just guessed he would hang the jacket on the stall door hook?
But, lets say the crook guessed that. I can see a crook who knew the jacket was there grabbing and tugging at it, until it went bang the first time. But, who tugs again after the first bang? !?!?!
This I gotta hear.
