The people involved are not wearing "Good Guy" and "Bad Guy" badges! How exactly are the police going to magically know who is "right" and who is "wrong"?

When the police come to sort out an altercation in progress, everyone involved is going to get tackled, rolled face down, have a cop kneel on your neck with his entire body weight, have your arms wrenched behind your back, and placed in handcuffs. That is the best, least physical outcome possible.
