Kinda worrying in many ways really - police taking guns from their departments and selling them to criminals and then saying "...but but I had no idea this was illegal or wrong!"

I doesn't even pass the sniff test.

Either the police are total idiots with no concept of right or wrong let alone knowledge of the law, OR they are willingly corrupt and will brazenly break the law to line their own pockets and to fuck with the consequences, which incidentally are pretty negligible because of the corruption and blind-eye turning of their buddies.

Both options are pretty troubling.
