The question to ask is if this was a white man in a suit with his car broken down on the road would he have been approached by Police with Guns drawn and would he have been shot had he walked away hands in air?
Would he have been described as one bad looking Dude.?
If the answer is no than the response was not objective and was based on the victims appearance.
That same question has to be asked after every such instance such as when a boy is playing with a toy gun in a park and is shot in 1.7 seconds and when a man carrying a gun he intends to buy in a store where he pulled it off a shelf is shot.
If the Police response is affected by Color of the persons skin then it very likely there some amount of Racism involved. If this same thing happens over and over again and is not addressed than it more than a little likely it is institutionalised.
That the police officer in question genuinely "thought" his or her life in danger does not mean there no racism involved.
