A violent protester, also known as a rioter, is someone who engages in disruptive and often destructive behavior in order to make a political statement. Rioters are usually part of a larger group of people who are protesting against a particular issue or cause. They may use physical force, vandalism, or other forms of disruption to make their point. Rioters often clash with police or other authorities in order to draw attention to their cause.
