The system functioned relatively automatically, and the prevailing system of racial meanings, identities, and ideologies already seemed natural. Ninety percent of those admitted to prison for drug offenses in many states were Black or Latino, yet the mass incarceration of communities of color was explained in race-neutral terms, an adaptation to the needs and demands of the current political climate.

For those who say that the war on drugs and the system of mass incarceration really isn't about race, I say there is no way we would allow the majority of young white men to be swept into the criminal justice system for minor drug offenses, branded criminals and felons, and then stripped of their basis civil and human rights while young black men who are engaged in the same activity trot off to college. That would never be accepted as the norm.

The mass incarceration of poor people of color, particularly black men, has emerged as a new caste system, one specifically designed to address the social, economic, and political challenges of our time.

Eventually [black men] are arrested, whether they've committed any serious crime or not, and branded criminals or felons for life. Upon release, they're ushered into a parallel social universe in which the civil and human rights supposedly won during the Civil Rights Movement no longer apply to them.

Incarceration rates - especially black incarceration rates - have soared regardless of whether crime has been going up or down in any given community or the nation as a whole.

If we continue to tell ourselves the popular myths about racial progress or, worse yet, if we say to ourselves that the problem of mass incarceration is just too big, too daunting for us to do anything about and that we should instead direct our energies to battles that might be more easily won, history will judge us harshly. A human rights nightmare is occurring on our watch.

Most Americans violate drug laws in their lifetime, but the enemy in this war has been racially defined. Not by accident, the drug war has been waged almost exclusively in poor communities of color, even though studies have consistently shown - for decades - the people of color are no more likely to use or sell illegal drugs than whites.
