Should have looked for prior responses. Didn’t mean to pile on.
It seems that a lot of people are cherry-picking the autopsy for what they want. True that he succumbed to cardiac arrest but the coroner's report cited the asphyxia as the actual COD.
If a person bleeds out then they will succumb to cardiac arrest but their COD will be exsanguination. Or if they get shot they may bleed out and succumb to cardiac arrest but the COD will be getting shot.
From one of the analyses of the coroner's report:
...the coroner's report said Garner died of “compression of neck (chokehold), compression of chest, and prone positioning during physical restraint by police.” It also ruled his death a homicide.
