The reason for the higher crime rates isn't directly relevant to the discussion of police "racial bias".

It's not? How do you know?

Police bias seems likes it could be directly related to crime rates (since it's the cops who do the arresting).

I'm not sure what your trying to say here? Are you saying that police framing black suspects is responsible for the statistics showing blacks being over seven times for likely to commit murder than whites, because that's the only way police bias could be the cause of the crime rates.

How did this "racial bias" manifest itself? Them acting like they believed blacks were more likely to be criminals than whites.

Judgements based only on race.

Well blacks are over seven times more likely to commit a murder than whites so you've failed to establish that the judgement was irrational.

I'm not arguing every white cop who shoots a black person is racist. Not even close.

Well somehow every prominent example sited by the type of people arguing for police being "racially biased" up on investigation turns out to be similarly justified.
