Somebody bragged
Somebody always does
This is why anyone with any sense would not go near any group like this. Bubba+beer+pot+blasters = Federalbuttslamprisontime.
If you're going to do this sort of stuff, you better be prepared for someone to brag, snitch, do something stupid, etc. I many be worried about the devolution of America, but I DON'T want to spend time in a federal prison.
