These Atlanta cops were clearly following their training and actually being "good cops" up until one of them made a rash, very rash and bad decision to shoot and kill the fleeing black man in the back from a distance of 8- 10 feet and then to compound his most likely criminal decision and their bad decisions, left him on the pavement for 2 minutes and put on latex gloves to pick up shell casing which is obstruction justice.
His, his partner's or anyone else's lives were not under immediate threat of death or grievous bodily harm when the decision was made to shoot the black man in the back from a distance of 8 - 10 feet. Case law, police policy, and even the manufacturer have found and state that "tasers are not lethal weapons". So to make a defence that cop feared for his life, his partner's or anyone else's life at the moment he shot the black man in the back from a distance of 8 -10 feet is simply not beyond a reasonable doubt. Remember they are supposed to be trained in use of force, in deescalation techniques and in decision making in these types of encounters.
Simple fact is why would a complaint of a black man sleeping in a parking lot lead to the shooting and killing of that black man in the back at a distance of 8 -10 feet not withstanding that they left that black man unattended on the pavement for 2 minutes and that they put on latex gloves to pick shell casings and thus obstructed justice?
Something very wrong with policing that allowed this to happen here, there and everywhere now, back then, way back then and ad infinitum.
