And then you have the scene were some chick is leading what appears to be a twelve year old around by the hand. What a great idea!! Lets bring the kids down to the protest so we can get a jump on the charges they'll be accruing for the rest of their lives.

With few exceptions, riots grow out of peaceful demonstrations where people just show up to show their support for whatever. Someone decides to have some fun by throwing a rock or bottle and it starts. Most peacefully demonstrations remain so. Riots are the exception.
As with everything, what you see on media is not the norm but the exceptions.
