IIRC he was at lethal dose levels when he died according to the autopsy report. The knee to the neck certainly didn’t help matters
Okay, since we are talking autopsy report: The coroner found NO bruising on his neck. The coroner went through layers of tissue at the point on the neck where there had been a knee. NO bruising at all, not at any point of the LAYERS of tissue that was examined. There just wasn't enough pressure being exerted on his neck to make a difference. He OD'd, and, unfortunately, he did it in a crowded parking lot with the police there and bystanders taking pics.
I have, since I am in my mid 60's, been watching the media gaslight us, over and over again, on sensitive issues. I have learned that it is not wise to take the "image" that they are showing you, again and again, and, only that image, as proof positive of some wrongdoing. Always pull yourself away from the emotion of the image and ask; What was going on before this picture was taken? It will take some days for the truth to come out; but, it always does. Do not trust the media.
