In that case you should check out the section
https://en.wikipedia.org/wiki/Race_and_crime_in_the_United_S...It seems clear to me given the evidence presented, that bias in the justice system does not account for the gap when it comes to serious crimes. Given this, in my opinion "Blacks commit crimes at around 5x higher rate than Whites" is a fair claim. I actually should have said 8x, I misremembered the article.
One interesting thing to me is that within parts of academia, it is not controversial to claim that Black people commit more crimes. Such academics seek the causes of this difference in various sociological explanations. You can see the discussion in the rest of the wiki article. But outside of academia a very different story is told. I believe that academics think that ordinary people cannot be trusted not to draw "racist" conclusions from the statistics about crime. Therefore liberal academics do nothing to dispel the myth amongst mainstream liberals, that Black crime rates are mainly due to bias in the justice system.
