Do you personally know any police officers? I do and, as a group, I've found them to be more racist than the general population. I don't know what the working definition of "white supremacists" is in this context but it doesn't make me blink.

This phenomenon happens with more than just police too—I've seen it happen with medical professionals, firefighters and EMTs as well.

0. Be a white person who has little to no interaction with non-white people in your day to day life.

1. Get a job where you interact with some of the dumbest people in the general public on the regular.

2. Some of those dumb people will invariably be, say, black. And you'll interact with way more black folks than the none you're use to interacting with.

3. Because you have no other association with that group your brain pattern matches and draws the connection.

4. Boom racism.

I find it hard to judge these people too hard because I haven't been "tested" in the same way. Like I want to believe I wouldn't fall down this pipeline but everyone says that.
