I'm not following you down your rabbit hole.
You can look at statistics as well as I. Black women, for example, represent 28% of the unarmed deaths at the hands of police and yet represent 12% of the population. It isn't just Breonna, amigo.

Which begs the question, why are 12% of the population so often implicated in a much higher percentage of crimes? People always point to the higher rate of incarceration as an argument to support "systemic racism". A much more meaningful statistic would be to look at the race of "suspects" in criminal cases. If only 12% of the suspects are black, but the incarceration rate is much higher, then that might be a valid argument. If the percentage of suspects is higher among blacks, then the incarceration rate would logically be higher as well. If 12% are committing 28% of the crimes, that's not racism. Just look at the news every morning where a suspect has been identified. What is the race of that suspect? There's your answer.
