"America has the world’s largest prison population. China, which has more
than four times as many people and nobody’s idea of a lenient
judiciary, comes a distant second. One in 107 American adults was behind
bars in 2011—the highest rate in the world—and one in every 34 was
under “correctional supervision” (either locked up or on probation or
parole). A black man in America is 3.6 times more likely to be
incarcerated than a black man in 1993 in South Africa, just before
apartheid ended."
