"Despite making up only 13 percent of the male population of the United States, black men constitute almost half of the male prison population, and on any given day, nearly a third of all black men in their twenties are in prison, on probation, or on parole. These black men are overwhelmingly from ghetto communities. The high levels of police surveillance, racial profiling, stiff penalties for minor parole violations, felon disenfranchisement laws, and general harassment of young urban blacks intensify their hostility toward the criminal justice system, and invite urban blacks to conclude that they are living under a race-based police state whose intent is to prevent them from enjoying all the benefits of equal citizenship and to contain social unrest."
