College protests became very popular during the Vietnam War era. In some ways, the protest did have an effect on the outcome. It did somehow force the war to end and the draft along with it.
As long as protests remain peaceful, I am OK with them, but the moment they turn ugly and cause damage, they need to be stopped. People being hurt or worse, property being destroyed is not a protest. They are crimes.
When local governments fail to protect the people they are responsible for, they need to be removed from office.
