Ta-Nehisi puts it in perspective:
Of the 2.3 million people in American jails, 806,000 are black males. African-Americans--males and females--make up .6 percent of the entire world's population, but African-American males--alone--make up 8 percent of the entire world's prison population. I know there are people who think some kind of demon culture could create a world where a group that makes up roughly one in 200 citizens of the world, comprises one in 12 of its prisoners. But I kind of doubt it.
