My view of this and similar police shootings, is many cops are too terrified and poorly trained to do their job properly. I understand you need to be prepared to deal with a suspect who may be armed and may attempt to do something stupid, but with many of these recent shootings that were caught on video, the victim was already contained, or was not showing any danger to the officer/s. Just because an officer is dispatched to investigate a report from a caller about some alleged perp, doesn't mean there is an actual problem which requires deadly force and a shoot first mentality. I don't understand how it was that the two people who appeared as unarmed and showing no threat to law enforcement or the public were in a standoff with police. Why were the police fearful of what the video showed of these people on the ground? The black guy was obviously terrified as I would be if black with the knowledge of recent killings by cops of innocent black victims. Why is it that, for even simple things like questioning the guy in NYC for allegedly selling illegal cigarettes, it should it turn into a takedown that caused a guy's death? What was it that was so terrible the guy had done, that it required physical actions by the police for what seemed to be a dispute over a misdemeanor offense?
As a volunteer firefighter, I deal with local small town cops on occasion, even State Police when responding to highway incidents here in MI. Any of them do a good professional job, though I have heard tales of inappropriate conduct by some poorly trained or some new officers with a Rambo attitude which needs attention to keep from becoming those with a shoot first mentality.
