Cannot see how anyone can defend this one: a knee on the neck of a man who had already been rendered harmless. Police acting in self defence? Nope, doesn't apply to a knee to the neck. Even a ten-year-old knows that, if you do not want to kill someone, then you do not press your knee down on their f-king neck.
Obama is right: how are you guys letting this shit happen in 2020?
Oh, and can someone please tell Trump that when the Chinese looked as if they were going to shoot the Hong Kong Rioters he started to threaten them with how indefensible that action would be? Fast forward to 2020 and, apparently, the Don is quite happy to shoot rioting Americans.

If he loses this election I am going to call it now: telling people to drink bleach and opening fire on American citizens in the wake of a man being beaten to death by cops.
