Protester Blocking Cars
There has been a lot of protesting recently here in the United States. Most of it has been peaceful, but some has turned very violent which is when a protest becomes a riot. People either think we are on the right track or well off the rails and passion is on display (sometimes for the better and sometimes for the worse).
Update: The video was removed from YouTube for showing violent content. We watched the video and there was no blood or anything like that, but it apparently violates their policy as was removed.
