In Atlanta, blacks are 54 percent of the population, but are responsible for:
100 percent of homicide
95 percent of rape
94 percent of robbery
84 percent of aggravated assault
93 percent of burglary.

That is entirely irrelevant to the claim that half of the population of blacks between 19-35 are criminals.
A mistake all too common though. There is a statistic that half the murders are committed by blacks. That doesn’t mean half the blacks are murderers.
