That’s the dumbest thing I’ve seen you write. It’s like saying “If you rule out gunshot wounds, JFK apparently dropped dead for no reason”.
Firstly, there is no conclusive link between Floyd’s drug levels and the heart attack that killed him. Secondly, as you would supposedly know, healthy people have died on smaller doses of opiates than Floyd had taken. Thirdly, his heart- the thing that the coroner concluded had killed him by giving out- was basically stuffed with rich creamery butter. As well as using meth and opiates he was also a tobacco smoker and cannabis user.
Chauvin’s optics were really bad, no doubt. But saying Chauvin killed Floyd ignores the fact that Floyd had been killing himself slowly for at least two decades before Chauvin showed up.
