The vastly different sentences afforded drunk drivers and drug offenders tells us who is viewed as disposable - someone to be purged from the body politic - and who is not. Drunk drivers are predominately white and male.

What has changed since the collapse of Jim Crow has less to do with the basic structure of our society than with the language we use to justify it. In the era of colorblindness, it is no longer socially permissible to use race, explicitly, as a justification for discrimination, exclusion, and social contempt. So we don't. Rather than rely on race, we use our criminal justice system to label people of color "criminals" and then engage in all the practices we supposedly left behind.

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.

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.

Of course in this age of colorblindness, a time when we have supposedly moved "beyond race," we as a nation would feel very uncomfortable if only black people were sent to jail for drug offenses. We seem comfortable with 90 percent of the people arrested and convicted of drug offenses in some states being African American, but if the figure was 100 percent, the veil of colorblindness would be lost.

When young black men reach a certain age - whether or not there is incarceration in their families - they themselves are the target of police stops, interrogations, frisks, often for no reason other than their race. And, of course, this level of harassment sends a message to them, often at an early age: No matter who you are or what you do, you're going to find yourself behind bars one way or the other. This reinforces the sense that prison is part of their destiny, rather than a choice one makes.

Most people seem to assume that this dramatic surge in imprisonment was due to a corresponding surge in crime, particularly violent crime.
