Contrary to popular belief, pacific demonstrations have very little power. That's why riots are an essencial tool for demonstrations like the ones we're seeing these days.

People like to give examples such as the civil rights' movement as the effectiveness of pacific demonstration, but that was just a good tactical decision made by Dr. King and other organizers, since they knew that police was ready to kill them at any excuse. In the case of black leaders of the time, any demonstration, even a pacific one, was able to make them subversive to the system.
