This is the sort of "terrorists" attack we need to be worrying about, the home grown Timothy McVey types out there. The Antifa folks and BLM (the feet on the ground, not those calling the shots) have no clue what sort of animal they are poking with a stick. This guy probably picked this target for no other reason than the potential for mass casualties of innocent bystanders.
Guys like this are all over the country. Red states, blue states, doesn't matter. Guys that have spent decades fuming over what they feel is the destruction of the Constitution and the government's constant siphoning off of freedom.
So long as the media keeps picking away and playing the game, this is all going to escalate as these guys get more and more fed up. Timothy McVey wasn't insane or crazy. He was a guy with a well planned and well executed attack in retaliation to perceived injustices. He got tired of seeing it and reading about it and decided to do something. Paddock was likely a very normal guy living a very normal life that decided somebody had to do something.
