I do not believe these events are coincidental. The Left has been seriously agitating for violence. No denunciation of these despicable acts.
The Left is very clearly signaling that they want the riffraff to engage in violence. It began with the talk about "resistance" from Hillary on down. Resistance to what exactly?
The graphic beheading.
The assassination drama.
The Republican shooting. (And I'm not buying for a second that the shooter ostensibly asked if they were Republicans or Democrats. I think that is a mere cover story fabricated by the media types to intentionally obscure the obvious.)
Blowing up the White House
Campus Antifa fascists
Professor bike lock assault
No, the Left is aching for violence.
