They quit being protesters when they threw the first rock/bottle and broke the first window.

They became rioters and looters and should be treated as such.

And for the folks who say it's just stuff so no one should be hurt or shot all i have to say you are part of the problem.

These actions should be taken by the head of said cities and if they don't stop it or can't/won't stop it then the state should get involved.

With the idea that these type of things will not be tolerated.
