They said that during the incident. The guy passed out and which the officers tried to revived him. But the paramedics or EMT said when they arrived at the scene. That the man was unresponsive, and so they taken him to the hospital where the doctors at the hospital weren't able to revive him.
Until we know the medic al cause of death, his death might only be coincidental with the knee stupidity.
Point is, we dont yet have even half the facts.
People are being whipped into a frenzy again over a short video that does not show the entire picture.
