Re: the Cleveland shooting - the video doesn't tell the whole story (at least there is a video though) and I am not familiar with all the facts, but...

The initial 911 caller told police that he/she thought the firearm was "probably fake", but that info never got to the officers on scene. The shooter was a rookie cop on the job less than a year (of all the officers in the area, why dispatch him to a potential firefight situation?). So lapses in police procedure seem to be contributing. If the officer killed the kid within 2 sec of the vehicle coming to a stop, when exactly did they ask the kid to put his hands up and observe that he didn't comply? Maybe they asked him from their loudspeaker before 0:21? Either way, to me it makes no sense for the other officer to drive the car into the park within 10 feet of the potentially dangerous suspect. Again, that is an act of escalation rather than diffusion that frankly is putting his partner on the driver's side at undue risk. What is the benefit of doing that? I don't mean to be a Monday morning QB, and I am ignorant on police rules-of-engagement, but it doesn't seem logical/effective. So is poor training/procedure also to blame (in addition to poor judgment)?

Why not use their loudspeaker at distance (handgun shooters generally have low accuracy beyond 25 yards) to ask any bystanders in the area to withdraw? Then from behind cover, they can have time to converse with the suspect, evaluate the risk, and discuss with HQ if needed. Why the need for such immediate violent response; the suspect was seated and not posing a threat to anyone at the time (i.e. there was no Hollywood style hostage standoff)? Shouldn't deadly force be the last resort? All of this seems to be circumstantial evidence supporting the theory that black life is not valued by some Americans (esp. in law enforcement). They wouldn't act this way if the suspect was a relative or friend, right? 

For perspective, the Richmond PD has not killed anyone in 7 years, despite the fairly dangerous climate in their city (but that PD is known for good community outreach). And they average  less than 1 officer shooting incident per year. So obviously there is a choice and violence is avoidable, unlike what Wilson claimed.
