Damn thieves. I bet the TSA union goons divide all the booty they steal (and the loose change that people leave that adds up).
No, they sell some of it to Pennsylvania, which then auctions it off for a profit. When I found out about it, I did some digging and found the government email address of the official in charge of PA's program (not too hard to do). He was indignant that I asked him why PA was acting as TSA's fence, and after a couple of nasty exchanges, he blew me off.
Like everything else in government, it's a damned racket!
