The FBI and DEA were paying a couple guys to turn information about Mexican drug cartels at the same time BATFE was paying the guys to smuggle guns to the cartels so they could see what would happen to the guns. And the DEA and FBI didn't tell the ATF they were informants.
These people make, what, 50, 60, 70 grand a year, each? Then they have known felons doing felonious stuff on a level that qualifies as an act of war against Mexico, and they don't bother telling each other.
THEN they complain that YOU finding out about these shenanigans is making their job harder! Oh, the poor little sad pandas. Here's mud in your eye.
Hat tip to Sipsey Street Irregulars! If you have a couple bucks, Mike would appreciate a donation - he's doing more investigative journalism while recuperating from SURGERY than all the rest of the national press corps, combined.
