First, it's not a criminal case and I don't have to prove any individual guilty. So there's that.
Racism is a very serious accusation, especially against law enforcement, so the standard of proof should be the same as in court.

Second, there's no altenative explanation that doesn't involve blaming the victims and saying they're asking for it. So there's that too.
Here you go again with victim mentality. People are not victims for simply being stopped by the police.

If the racism argument isn't true, something else has to be causing it. You haven't provided anything remotely plausible to explain those numbers.
I appreciate I'm speculating, and probably have not identified the reasons why there are statistical anomalies. But to say it's racism is equally as speculative. You have only one answer.
