Is this calling the Civil Rights movement domestic terrorism?

Well BLM isn't really an organization, the people protesting aren't trained to deal with the police. So when you have a bunch of angry young people, and the police try to make them leave by force, it's only going to escalate the situation, which is exactly what the police and news commentators want. The police want to make the protests look like violent thugs, to justify their force, and news outlets see a huge spike in ratings when they can show chaos and carnage.
