I don't really see the racism slant the article is trying to paint all over this stupidity.
Because there isn't a systemic problem with people who look like you getting shot for no reason when they talk to the police.
There is a systemic problem with certain ethnicities propensity for crime - hence violent interactions with the police that happen as a result.
Most cases the media publicizes turn out to be flat lies, such as the 'hands up, don't shoot'.
