The war on drugs has been the engine of mass incarceration. Drug convictions alone constituted about two-thirds of the increase in the federal prison population and more than half of the increase in the state prison population between 1985 and 2000, the period of our prison system's most dramatic expansion.

One in three young African American men is currently under the control of the criminal justice system in prison, in jail, on probation, or on parole - yet mass incarceration tends to be categorized as a criminal justice issue as opposed to a racial justice or civil rights issue (or crisis).

For reasons that have stunningly little to do with crime or crime rates, we, as a nation, have chosen to lock up more than two million people behind bars. Millions more are on probation or parole, or branded felons for life and thus locked into a permanent second-class status.

To make matters worse, federal drug forfeiture laws allow state and local law enforcement agencies to keep, for their own use, up to 80 percent of the cash, cars, and homes seized from suspected drug offenders. You don't even have to be convicted of a drug offense; if you're just suspected of a drug offense, law enforcement has the right to keep the cash they find on you or in your home, or seize your car if drugs are allegedly found in it or "suspected" of being transported in the vehicle.

For African American children, in particular, the odds are extremely high that they will have a parent or loved one, a relative, who has either spent time behind bars or who has acquired a criminal record and thus is part of the under-caste - the group of people who can be legally discriminated against for the rest of their lives. For many African American children, their fathers, and increasingly their mothers, are behind bars. It is very difficult for them to visit. Many people are held hundreds or even thousands of miles away from home.

I think it's important to encourage young people to tell their own stories and to speak openly about their own experiences with the criminal justice system and the experiences of their family. We need to ensure that the classroom environment is a supportive one so that the shame and stigma can be dispelled.
