Interesting to see that "white" managed to lead the spate of pejoratives toward the end of the article ("Each of 4 white, ignorant, racist asshole police officers"). I've been the victim of interracial crime, at least once due to my race. I did not consider the race of my assailants to be anywhere near the top of the list of characteristics to which I should like to object.
Without any facts, I'm skeptical. He should either move on with his life, or make a formal complaint and/or a lawsuit. Taking the middle road with a story with few details on Medium doesn't help anyone.
It could be the same with all of these stories of law enforcement behaving very badly. It seems like a weird thing for so many disparate people to be fabricating. Maybe there is a problem and reporting it isn't getting toward a solution? If it happens to you, silence is almost certainly the wrong course of action. I don't want to believe there is an endemic problem with law enforcement either. What I want shouldn't matter at all.
