A goal of violent demonstrators is to spur law enforcers to take actions that can be exploited as acts of brutality in order to generate sympathy for their cause, and/or to anger and demoralize the opposition.[1] Crowds can use a range of tactics to evade law enforcement or to promote disorder, from verbal assault to distracting law enforcers to building barricades. The more well-planned tactics occur, the more purposeful the disorder.
