Unfortunately deaths by actions of police officers usually go about at a slow pace.
Due to this fact and it was again with this situation, the calls out of racism went out and spiraled out of control, enhanced no doubt by the private video that went online quickly.Hopefully things will quiet down until the charges and the ex-cop go to court.
I dont think this was a direct case of racism but one of a physical arrest that went haywire incited by bystanders who were directly interfering.
