Today there are more African-Americans under correctional control, in prison or jail, on probation or parole, than were enslaved in 1850, a decade before the Civil War began. There are millions of African-Americans now cycling in and out of prisons and jails or under correctional control or saddled with criminal records. In major American cities today, more than half of working-age African-American men either are under correctional control or are branded felons, and are thus subject to legalized discrimination for the rest of their lives.

I do believe that something akin to a racial caste system is alive and well in America.

Now that's hard for many people to believe, given that the media image of a drug dealer is a black kid standing on the street corner with his pants sagging down.

In fact, in some countries there are actually voting drives conducted in prison! But here in the U.S., we seem to take the idea of democracy a bit less seriously and people are denied the right to vote not only when they are in prison, but also upon release in many states.

There is a tremendous amount of confusion and denial that exists about mass incarceration today, and that is the biggest barrier to movement building. As long as we remain in denial about this system, movement building will be impossible. Exposing youth in classrooms to the truth about this system and developing their critical capacities will, I believe, open the door to meaningful engagement and collective, inspired action.

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.

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.
