Police in Rochester NY shut down two pawn shops and charged them with $15m in stolen tool sales. They would give addicts lists of what they wanted. When caught they claimed they were doing it to cut down on home invasions. The police figure there are additional shops like these around.
I have seen them post on CL unopened boxes for years, but figured they had to be legitimate or they would have just been shut down. I mean, how hard is it to demand to see receipts? Rochester is a pretty small town. Since it took years, I guess harder than I thought.
