This makes Black people not trust police officers. Because police officers seem like they are always trying to find some reason to mess with you, violate your civil rights, and "hem you up." And you visibly see that they don't seem to do this with white folk.
Again, I'm not even talking about the racist cops here, of which there are many! I'm just talking about the ones who just go with the flow of what the system wants them to do.
Black cops do this too. Black cops pull over Black drivers.
