Answer 1

when these type of protests escalate into violent confrontations, like 1960's, these groups become acting crowds.
When all this happens and they are going to protest and becoming an acting crowd, they are doing a civil disobedience. Any actions we take to chance the policy or law by refusing to obey that law, these actions may be violent.
