I don't think choking someone to death can ever be considered accidental. The cop employed an illegal maneuver, the justification given for force was resisting arrest (victims hands were clearly held up and no movements were made toward any of the officers), the entire thing was filmed, the victim died, and the grand jury declined to indict the cop who continued to choke him despite multiple cries that he could not breathe.
The officer declined to believe Eric Garner and continued to choke him, while he was on the ground, and the man died. The coroner ruled it a homicide.
That is our current system. The problem lies with the police who show little to no interest in protecting citizens safety during an arrest, some of whom frankly show disturbing sadistic and sociopathic tendencies, and system that protects them because they have a "stressful job."
So my position is that there is a massive correction that needs to start now with every single police precinct in America. We need to retrain all police, construct and communicate a new system of correction and redress when brutality occurs (one with a special prosecutor appointed rather than a DA), a new set of automatic penalties for specific actions (like the ones described here and many other areas) that include immediate dismissal and criminal charges, and better non-lethal equipment and training for conflict resolution.
Over 100 people were killed by police last month. That's more than 3 per day.

To continue to pretend that the problem rests with individuals who do not behave well enough in encounters with the police and not with an increasingly violent, militarized police culture that views itself as at war with its citizens will only perpetuate the problem. It seeks to deny that a problem actually exists. This will only get more people killed and result in more civil strife between affected communities and police.
The solution has to include massive reform of our police cultures and facilitate re-engagement between precincts and their communities.
