Problem is backing down. When you’re in a heightened state of alertness and your body has primed you for fight/flight, it’s hard for either side to calm down. Even in domestic disputes where people know each other and at least think they’ve “loved” each other and care. It’s hard to back down.
So seeking confrontation is the problem from both sides. Some people want to protest, some want to confront. And the police prepare for worst case ... which means confrontation which escalates...
Then you have opportunists who just want a fight .
