Here's my suggestion to those who think the police aren't trained well enough, or use excessive force in the exercise of their duties, or who think they can subdue a belligerent, resistant offender peacefully: Agree to be deputized and on call for just such situations where the police are arresting someone and a mob forms threatening the police. We can try your way. There won't be any arguments then about what works. It's like being a conscientious objector in Vietnam. They are the first to pick up the gun when things start going south. How do I know that? First hand experience. Principles and moral judgements are easy when you're viewing from the safety of the sidelines. Being in the mix is something else.
