There were no riots. No one really cared. The police cam video shows what happened to Timpa to be worse than what happened to Floyd. While Timpa was handcuffed and restrained by the cops, he died in front of them while they laughed. And Timpa had called 911 to seek help because he had run out of medication for his schizophrenia and was in distress.

The system worked. The officers were charged and put in prison.
