1st Amendment does not grant any citizen to commit or incite violence. One can not yell fire in a crowded theater.
When any violence is committed against an innocent civilian as was the situation in Virginia today, it is the definition of terrorism.
It matters little which laws will be used to prosecute the terrorist action today, just prosecute to the fullest action of law.
The DOJ has no need to waste federal tax dollars for an investigation into this incident. The state of Virginia is perfectly capable of prosecuting the person who did this.
I am sick of the DOJ getting involved in cases like this. Let the states handle their crimes and criminals.
I also think it is way too early to label this terrorism. Let us see what his background is. If he has any overt political ideology or ideas. Any writings... If it went down as described, I think he is just a crazy SOB who was pissed off at a bunch of piss bomb throwing and screaming lunatics. Murder, attempted murder....criminal.
