It's like they didn't treat him as a living being. You wouldn't choke cattle marked for slaughter like that, much less for so long. For all the rightful outrage about shootings they at the very least are still volatile high pressure situations, where there is at least a shred of a benefit of a doubt that allows you to make a bit of sense of them. But this is something else entirely. And it says something about the relationship between the police and public that four officers aren't fazed at all by being filmed choking a subdued man who says he can't breath. At that point already they have taken things waaay too far already and proven themselves unfit for duty imho.
We had a cop on this forum who referred to people he had arrested or knew had been dealt with as oxygen thieves or wastes of space or something. A couple of posters expressed concern at his dehumanising comments and I think this case shows why. A cop who doesn't see the man he's arrested as a citizen who is entitled to due process. Instead he decides he can do whatever he likes behind colour of authority and he just doesn't treat him as human at all.
America is a sick country.
