Huh. So an Executive Agency in the government decides it wants to push a meme about US guns fueling Mexico's violent crime problem, can't get the corroborating trace data to support such claims, and resorts to taking the matters into their own hands.
And it's all the NRA's fault.
What we know for sure at this point. (Obviously abridged, since to try and capture the entire timeline here would take up wayyyyy to much space. You can check out the Gunwalker time line at the National Gun Rights Examiner, here.) The ATF forced multiple gun dealers in Arizona to sell guns (2000 plus at this point, it could be more) to people those merchants knew were straw buyers, but were told point blank by the ATF to sell to anyway.
Those buyers were surveilled and were NOT interdicted before their purchases were turned over to gun runners. As a result, Border Patrol Agent Brian Terry was killed in a fire fight with gun runners in Dec 2010. Found at the scene were two guns traced to Operation Fast and Furious. Another federal agent, Jaime Zapata, was killed in Mexico with a gun linked to a similar operation in Texas.
We have senior Justice Dept officials on record as using the results of this operation as a justification for the border states rule on multiple sales of long guns.
But all this is the NRA's fault? Really?
As Ron White would say, I don't think so, Scooter.
