True enough, Isaac. We DO have riots that have been claimed as being "non-violent" - though the looting, car-window breaking, and burning vehicles make you wonder about the definition of "non-violent."
I reviewed the thread and realized it included certain details and omitted certain other details regarding George Floyd, whose death triggered the riots in the thread title.
George Floyd was arrested due to passing counterfeit money. When he was arrested, it was later determined that he had illicit drugs on his person, but somehow he managed to put those drugs in his mouth. We will never know what he thought, but the drugs were poorly wrapped and he ingested drugs that contained fentanyl. He had a heart condition and there is now a considerable furor over whether Officer Chauvin was the primary cause of death or whether cardiac failure due to a drug overdose was the primary cause of death. His family commissioned a separate medical exam but the original autopsy apparently detected the drugs in his system.
