So you don't think there's any margin of error in law enforcement being more likely to detain a black person (even when they've done nothing wrong) and more likely to turn the other way with a white person (even when they see them committing a crime)?
So you're asking if I think a cop will witness a white person commit a crime, but not do anything about it because they are white, and that this is somehow systemic in law enforcement? Thats a resounding no.
Cops will detain any person even if they have not done anything wrong if they believe they will cause a disturbance. Will some of these people be black? Of
Course. Will there be a handful of cases where racist officers use their authority to enact Hateful prejudice? Of course, they are people just like us. But hateful prejudice is not systemic. With any statistical sample there is a margin of error, irregularities, exceptions, etc. but we're talking about pretty wide margins.
