The exact opposite of everything you say is relevant too. What is the point of championing the possibility this has nothing to do with race if there's no proof it's all pure coincidence? Just because the officer wasn't wearing a klan hood doesn't mean give them, their police department or American law enforcement in general the benefit of the doubt, right? What good comes from ignoring and staying silent about police forces in the U.S. allowing disproportionate systemic subjugation of minorities on a functional level just because there's no concrete evidence this one individual shot at these kids because they were black? Why champion the possibility this one cop isn't racist deep down when "being racist at heart" has little to do with the systemic, functional racism of American police?
And police killing unarmed people and showing little to no effort of making changes is what damaged relationships with law enforcement; those killings and the lack of concern from the blue line are what undermines the legitimacy of all life, not just those of minorities (since unarmed people of all creeds, ages and races get executed by police each year). People bringing up race are acknowledging reality, the full context this incident occurred in. If it sounds to you like they're asserting the police shooting occurred because these children were black, rather than engage in the frivolous activity of defending the off-chance this had nothing to do with race, remember that these forum goers are not on a jury, are not judges or prosecutors, and instead consider why they come to that conclusion instead. Perhaps direct your efforts toward convincing police (an institution with specific practices and incentives) that they need to change, rather than direct all your effort toward reminding people (individuals who are voicing personal concerns of the aforementioned institution) who are sickened by these killings by police that they can't prove the existence of racism in an individual's mind.
Once you can prove people have no reason to expect racism and unnecessary violence from police, then you can chastise people for "making it about race" without being ridiculously myopic.It's a waste of everyone's time to criticize the oppressed without first providing
an established record of critique of the oppression.
