There is a lot of evidence, that is easy to find, that laws criminalize African-Americans (e.g., drugs abused by poor African-Americans are criminal and result in prison; those abused by wealthy white people are sicknesses and result in treatment); that police harass and are brutal toward them (e.g., driving while black, predictive policing, and all the well-documented brutality and racism), and that prosecutors and courts sentence them to disproportionately harsh sentences, including long probation and loss of voting rights, and the inability, with a conviction, to get employment.
In my city I've seen the police in action many 5 times. Twice, it involved clear abuse and harassment of peaceful African-Americans. It's just my anecdotal experience, but are the odds?
Your argument is decades-old at this point; we know so much more now. What do you think of all that's been learned in the meantime (and by learned, I mean learned by the wealthy white population - it was known by some for generations)? Are we going to just rehash decades of learning? Nobody is making the points you are arguing with.
