How does this NOT have a thread already?
This one seems to call into question the "just do background checks" argument, as this guy didn't just go through a background check, but a full security clearance check, and still wasn't caught as the obvious nutbar he so clearly was.
Also touches on the old AR-15 is evil argument, as this guys weapon was a standard issue shotgun....which he used to shoot, then take the weapons of, one of the peopel protecting this base.
Seems his motive remains elusive, but as is usual the media is trying to pin whatever it's cause-de-jour of the moment migth be and speculating wildly.
Predict incoming "He was a right winger/left-winger" arguments on radio.
What it is is a damn shame. We lost some good people, real servants of the Nation, yesterday....to yet another nutbar who shouldn't have been ont he street, much less given a security clearance.
