My son has been active helping our local BLM and similar groups, teaching them non-violence tactics, etc. so I've learned a lot from him. BLM is a diverse group. They differ from city to city. In our area, where there have been quite a few innocent blacks killed by LE, not everyone belongs to the local BLM. Some groups have organized on their own because they support non-violence. The groups protest together, but when violence begins, my son's group takes evasive action - they watch for early signs and move away. They know how to ramp up a protest without destroying property or putting anyone at risk. They also know how to avoid the LE tricks used to put protestors in bad situations (google "kettling").

Black protest groups are not a monolith. They're all different and they engage in protest in different ways. Same with Native American and other groups. Groups are also on the watch for agents provocateur, people who disguise themselves as protestors in order to engage in and incite violence in order to make protesting groups look bad. My son even teaches a class on how to spot and avoid them in a protest or at a meeting. He also taught me never to let police into my home without a search warrant. Calmly step outside, close your door behind you and very politely tell them you'd like to help, but you can't and they can talk to your lawyer. The latter is why I'm so uneasy about them swiftly going into Justine's home after her death. There was no good reason for that.
Americans are uncomfortable with peaceful public protests, but they're common and accepted in Europe. Americans need to learn to become comfortable with non-violent civil disobedience. It's part of our history. Our ancestors engaged in it.
