It doesn't really stop there either, they are more likely to be convicted of the same crimes and then get longer sentences. They are less likely to be offered probation. This eliminates huge percentages of men permanently from POC communities. It is possible that this process can be blamed for the social issues present in the inner city.
"The New Jim Crow" covers a lot more in a lot more detail. I would strongly recommend the read.
The parent's point isn't about whether they are acquitted, it's that if you were to commit a crime as a POC, you are more likely to be arrested than if you had committed that same crime as a non-POC. In both scenarios you committed a crime, but in one of them the system never has a record of it. This is why arrest rates and crime rates are different: if a POC is more likely to get arrested for committing a crime, the arrest rates by race (POCs get arrested more) will not reflect the crime rates by race (differences are generally smaller).
