An infamous thief, when asked why he robbed banks said, "cuz that's where the money is." My point is why rob a pawn shop--I know they keep sometimes large sums of cash on hand, but if they sell guns, everyone behind the counter is packing a sidearm.
LOL, you really don't know about pawn shops or read the article I see. You could make the same argument about mom and pop convenience stores or any other non major corporate small business and possibly be right. All these businesses get robbed and some types get robbed often. So "Why?" is a non-issue.
Maybe you missed it, but the guy was actually shoplifting a drill when he was caught. He wasn't robbing for money.
