If they start violence, put a fucking bullet in their head. Enough of this shit already.

Blowing up cars is not a protest, it's an act of terrorism. Threatening the life of the president and trying to incite violence against him is terrorism against the people of this country. They have the right to march around and complain. They don't have the right to try to convince people to commit violence or to commit violence themselves. The only way is putting them the fuck down once and for all. Then, maybe others will take heed.
