This growth is not attributable to increased offending rates, but to increased punitiveness. Being "tough on crime" became a political mandate. State and federal legislatures imposed mandatory minimum sentences; abolished or radically restricted parole; and adopted "three strikes" laws that exact life imprisonment for a third offense, even when the offense is as minor as stealing a slice of pizza. Comparing the ratio of convictions to "index crimes" such as murder, rape, and burglary[3] between 1975 and 1999 reveals that, holding crime constant, the United States became five times more punitive...African-Americans have borne the brunt of this war. From 1985 to 1991, the number of white drug offenders in state prisons increased by 110 percent; the number of black drug offenders grew by 465 percent.[7] The average time served by African-Americans for drug crimes grew by 62 percent between 1994 and 2003, while white drug offenders served 17 percent more time.[8] Though 14 percent of monthly drug users are black, roughly equal to their proportion of the general population, they are arrested and imprisoned at vastly disproportionate rates: 37 percent of those arrested for drug offenses are black as well as 56 percent of those in state prisons for drug offenses.[9] Blacks serve almost as much time in prison for drug offenses (average of 58.7 months) as whites do for violent crimes (average of 61.7 months).[10]...If white male babies faced anything like such prospects, the politics of crime would look very different. We would almost certainly see this as an urgent national calamity, and demand a collective investment of public resources to forestall so many going to prison. Politicians would insist that we reduce criminal penalties, decriminalize nonviolent drug offenses, and promote alternatives to incarceration. The fact that there aren't such calls today—or that if there are, they go largely unheeded—suggests that our criminal justice system is sustainable only because its disparate effects leave the majority off the hook.
