I have a few that are close personal friends of mine and I can tell you that, at least my police friends, are very intelligent, warm, and funny people. And I can assure you they are not racists in the least. Far from it.
Are there bad apples? Sure. But the majority that I’ve personally met are great folks.
The one common trait I do see is that they like to step in if they see an injustice…I’m more picky and let sleeping dogs lie until it gets to be too bad to ignore. They step in way earlier than I do. Which spooks me sometimes but they are probably way more used to it and know they can have their uniformed buddies on the scene in just a couple of minutes. Me, I can’t say that.
