Technically, CBS is right.
They reported a story of an American trying to smuggle an “assault rifle” across the border into Mexico. It was “hidden” in plain sight under the hood of a pickup truck. CBS “tracked” the assault rifle to a evil gunstore in Arizona where the gun was purchased. Then they went on to assume that this kind of gun smuggling was going on all along the border.
They are right that they reported on f&f first, but they were part of the coordinated effort to destroy the 2nd ammendment.
It was posted here on FR complete with pictures.
