It’s odd to me (a white dude) that their races are such a focal point, I understand why it seems weird but it’s nothing really new. NWA sang about “black police showing out for the white cop” in 1988. It’s always been cops killing minorities, a majority of killer cops are white, but plenty of them have been other races as well. It’s the police as an institution that kills people, which certainly comes from being founded upon racist ideologies, but the race of the individuals who follow that institution isn’t of much significance to me.
