It looked to me like he was having an anxiety attack. The cops only made that worse. Murder? I don’t think so. But they did not handle that situation properly. There was no reason to kneel on his neck to control him. And the signs were there to have known what was going on.
It has come out that the neck kneeler had a bad history with this douche bag and knew him pretty well. I see this may have caused some of his responses to be pushed over responsible limits.
