None of what you say counters their point. At the end of the day African Americans commit a disproportionate amount of crime, it would be a miracle if they didn't have more prior convictions on average.
All the stats we have focus around arrests, charges, convictions, so any systemic racism in enforcement is included.
African Americans being arrested more per capita for a crime is not inherently the same as committing more crime per capita.
I have a hard time figuring how you could ever prove your claim, because how do you show who committed crimes that were either not suspects, or crimes that weren’t discovered or reported?
They're trying to denounce the racial aspect of likelihood of being targeted/prosecuted, by going "African Americans are more likely to be involved in crime already" - which is also inherent on racial biases and profiling in the police and criminal justice systems.
The point is that they can't jump to racist dog-whistles and then pretend like race isn't a factor in targeting to begin with.
