That may be true, it's not for me to decide. Feel free to ping me when the authors are struck off for this abuse. Until then I'll assume that their autopsy is valid. Anyway, you're just confusing matters if you keep saying "the autopsy" without referencing the one you mean. I'm not even asking you to acknowledge the other one explicitly if you don't like it.
Also, you're splitting hairs about the exact way that George Floyd was killed by the police. Both autopsies ruled homicide. The only people interacting with him were police officers. According to both autopsies, the police therefore killed George Floyd. We do agree on this, right?
