These feral mobs have been empowered by Holder and Obama. White cannon fodder who voted for the race hustler in the White House are now starting to get their reward. PC does kill and those in “journalism” who write articles that hide the identities and motivations of the attackers and delete explicit comments are getting people killed as sure as if they shot them themselves.
Blacks have been doing this for many years. I remember Miami in the 70s with National Guard posted on corners. Maybe it’s a genetic thing.
