Oh c’mon... I’m the first one to admit that we don’t always hear the truth behind some of these events (see the OU Bombing for instance), but why are you assuming this was some sort of “black op” event??? There is NOTHING thus far to indicate anything of the sort...
Black trenchcoat, no motive, reports of other shooters and shots fired later, another random-rage shooting by a young person in a whole line of them, exactly in time to push new onerous laws at the federal level—come on, there is lots of evidence!!
—where do you get “smoke bombs” anyway? That’s military/police hardware.
