sidenote: if by any miracle he didn't die (though how one can't die when the blood flow to the brain is cut-off?) then the 8 minutes of sadistic torture would have probably not even registered on anybody's radar. In the video it is so obvious that the police guy is immensely enjoying that power trip.

It is puzzling why the society still allows police to apply chockhold, neck pressure, etc. - such actions affecting breathing and circulation are naturally causing involuntary convulsions which police happily interprets as "resisting", and thus they get and use their right to escalate the pressure/hold until the "resisting", ie. the convulsions, stop which frequently means death.
