The difference in criminal activity between blacks and other American subgroups is so large that it is hard to imagine any regressions making much of a difference. Black males are 6% of the population and commit 53% of the murders, more than the other 94% of the population combined. Keep in mind that there are more poor whites than total blacks in the country, but the black crime numbers are higher than the total white crime numbers.

Finding the root causes of the disparity would be a fascinating sociological challenge, if we had the courage to pursue it.
