I hate having to raise this point, but there's another ugly reality here. Namely that black people are disproportionately represented in crime statistics.

The percentage of black people in America is around 13%. But the percentage of homicides committed by black people is around 50% of the total.

If you're over-represented in crime, you'll be over-represented in police interactions, and therefore, if the police force are violent, abusive, unaccountable bullies, you'll receive a disproportionate amount of that violent and abusive treatment.

To be clear, the actual percentage of black people committing these crimes is tiny. I've written about it here. But focusing on one disparity without acknowledging the other gives you a skewed picture.
