A “protest” is always an action taken by one or more persons that challenges a de jure reality (a bad law, e.g., illegal marijuana) or a de facto reality (where people, not governmental fiat, are the problem, e.g., racism). Protests are always disruptive and often illegal, else what is the point? Many if not most protests are instances of “Civil Disobedience” and in consequence expect police involvement and even jail time. Protests are NOT necessarily non-violent, or non-destructive of private property (the best minds suggest that non-violence is the proper tactic when their side does not have fire power enough to take on the opposition (Gandhi preached non-violence because the ruling Brits had all the weapons)).
