An unarmed man, already cuffed and lying down in the road, died after a 220-lb or so (now ex-) policeman kneeled with his knee on the guy's neck for 7-9 minutes, even as passerby are filming and some are saying, "stop, you're killing him".
Other policemen -- now known to have earlier used excessive force (knocking a teenager's teeth out) -- stop passers-by from helping the guy on the ground, and appears to be maneuvering to keep the incident from being filmed.
The guy doing the kneeling stayed kneeling on the dead guy's neck for about 2 1/2 minutes AFTER the guys' bowels evacuated...presumably the time of his death.
The paramedics found no pulse when they showed up.
And the guy doing the knee on the neck? Put his hands in his pockets while it was going on. Not exactly a subliminal sign of fear for one's life or safety.
Did you even bother to watch the full video?
Yes, I watched the video. My take away was the same as yours. Whats the rant about?
