I’ve never been to the USA, but here is an article that essentially says the same thing:
vox.com: “I’m a black ex-cop, and this is the real truth about race and policing”.
We are rooted in racism in spite of the better efforts of Americans of all races to change that. Because of this legacy of racism, police abuse in black and brown communities is generations old. It is nothing new. It has become more visible to mainstream America largely because of the proliferation of personal recording devices.
I’ve never been to the USA, and I have a hard time wrapping my head around the US race discourse. For example, in continental Europe, you would rather not use the word “race”, it would be inappropriate and most likely identify you as a racist! Whereas in the US, it is used as a neutral term. Of course we have racism here (duh), but the discourse works rather differently.
