Confirmed: Mexican military helicopter was shot down with ATF supplied, 'gunwalked' rifle

This was a 50 caliber rifle supplied to the drug lords by the insane ATF, under the Obama administration.

"CBS News has learned that the recent case of a Mexican military helicopter forced to land after it was fired upon is linked to the ATF Fast and Furious "gunwalker" operation.

Drug cartel suspects on the ground shot at Mexican government helicopters two weeks ago in western Mexico, forcing one chopper to land. . . .

Among the seized weapons are guns sold to suspects as part of the ATF sting operation, sources say. That information came from traces of serial numbers." (end of CBS quote)

As Congressman Issa told Fox News :
This is not a discovery process of what happened--we know what happened. We know that this administration, at the highest levels, approved a process that allowed thousands of high-powered weapons--basically AK-47 and M-16 look-alikes--to go to the worst of the worst on both sides of the borders, that those weapons have been used to commit crimes, and they have led to the death of federal agents on our side of the border, obviously, also Mexicans on their side of the border. This is known. The real question is what were they thinking.
