I think about this post by Freddie deBoer all the time
The irony of our vibrant and necessary police reform movement is that it’s happening simultaneously to everyone becoming a cop. I mean everyone — liberal, conservative, radical and reactionary. Blogger, activist, pundit, and writer, obviously, but also teacher, tailor, and candlestick maker. Cops, all of them. Cops everywhere. Everybody a cop.
Read the whole post. It's great.
There is a deep tension within seemingly progressive circles. In some ways, it's just the paradox of toleration. But I think there's more to it. Being a cop makes people feel powerful, it's a way of exercising domination over people. That's true of the cops, but it's also true of social cops.
