I don't doubt there were people of different colors trying to exploit the situation. I would shoot them all. That said, it still remains, when the truth of George Floyd situation comes out, the police are not likely to be convicted under Minnesota law. Federal? Maybe.
These morons that are more interested in stealing free **** and destroying property for no reason, aren't going to stop long enough to understand what the law says, or what the circumstances were.
FWIW, I have a good friend, who was in the same situation as Floyd (resisting arrest, handcuffed behind his back, face down on the street, knee on back of head, unable to breath) when a policeman rescued him. He got 25 years. My friend is black, but has a much different view of things than you seem to have, including black lies matter.
