I wouldn’t be surprised if the race of the band director did place a part, but I’m pissed at what happened either way.
By some more nuances definitions I’ve heard it may be technically true that the black cops weren’t racist. However, it is possible to treat someone poorly because of the color of their skin even if it matches your own. Maybe the cops consider themselves “one of the good ones”, maybe they just believe that they are able to power trip a little harder against certain races because it’s more socially acceptable, or maybe they don’t want to stand out against their white peers and just do what they do.
I honestly didn’t watch the video either though - maybe a black cop was the first to escalate it so the last hypothetical isn’t a strong one. I’ve just seen enough videos like that this week and don’t want to get more upset by watching one more.
