Marijuana use by black residents of Washington DC is only slightly higher than among white residents. Given that blacks are slightly more numerous in DC than whites, we should – if criminal justice were fair – also see only slightly more blacks arrested for marijuana use. Surprise, surprise: that’s not the case. In 2007, 91 percent of those arrested for marijuana were black. Adjusting for population, African-Americans are eight times more likely to be arrested.
(source, source, the drawing makes it look like blacks are more than 11 times more likely to get arrested – 8*11=91 – but that doesn’t take into account the fact that blacks are slightly more numerous in DC – hence the correct number is 8 times)
A similar pattern for Chicago (where whites are more numerous than blacks):

And this is the case for many if not all types of crimes. The racial distribution of inmates in U.S. prisons is highly negative for black Americans. Whereas they only make up 12% of the total U.S. population, they represent more than 40% of all inmates. It’s obvious from the case of cannabis that this difference isn’t due to a higher level of involvement in crime. I wonder, could racial profiling perhaps explain something? Actually, I don’t wonder…
