So, this guy had been brought in for questioning by the fbi twice. He was a known accomplice with a member of isis. He obtained a statewide firearms license. He worked for the federal government and had security clearance, so he obviously passed a federal background check.
And the libtards think governments involvement would have prevented this. I mean, that's just as insane as blaming the nra or the inanimate object for the problem, and other stuff they say and do, so I'm not surprised, but, please, tone down the crazy.
