It may, pretty much, be a rogue operation but the person that runs it is at the President's discretion.
How do you know that the -resident is not run at the state department’s discretion? Without bill clinton, bambi is back doing community organizing.
Bottom line is the corrupt Mexican military and police are supplying the cartel thugs with US weapons.
Another source is Central American countries which is a cheap source for AK’s
Another note is that the MSM never points out that it was the US gun shops that tipped off the ATF about the straw purchasers and multiple gun sales. Only to be coerced into playing in the ATF sting operation. It's a good thing they documented their work with the ATF otherwise they would be in jail now.
