> demanding charges against the other officers present that seem extremely hard to justify legally speaking, and calling for Minneapolis to burn until that happened

Demanding a moderate response in polite terms has been demonstrated to get you nothing. Nobody making those demands realistically expects them to be met. There is a vague hope that some incredibly watered-down version might come about.

It's rather like pushing at a stuck door that's become stiffer over time and ultimately locked. If you shoulder-charge it, maybe it will budge.
