There is a certain phenomenon though... a cop can shoot a black person for no reason and they'll all just pretend there was a reason and not punish the cop at all. Meanwhile a cop can get caught on camera being like "lol yeah dude, I hate black people so much" and it's actually more likely they'll get fired. Even though it's a thousand times less bad than murdering someone for their race, it's bad in a sort of undeniable way. They don't have the cover of some life and death crisis, so they just fire them.
