Any empirical work will involve questions of whether you are truly measuring the effect you want to measure. However I am claiming, based on my knowledge of the field, that researchers have adequately dealt with this, and come to the conclusion that Black people really do commit more crime, after taking into account all observable economic and social effects. Another replier has already mentioned that you can measure crimes that are less subject to bias in prosecution (like homicide. If there was an easy way to explain the apparent excess of criminality in Black people by these means, I'm sure I would have read about it in the academic literature.
