Our system of mass incarceration is better understood as a system of racial and social control than a system of crime prevention or control.

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.

Many people don't realize that financial incentives have been built into the drug war that guarantee that law enforcement will continue to arrest extraordinary numbers of people, particularly in poor communities of color, for minor drug offenses that get ignored on the other side of town.

People on probation and parole are typically denied the right to vote, and in eleven states people are denied the right to vote even after completion of their sentences.

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.

The fact that people of all colors have been ensnared by the drug war helps to preserve the system as a whole from serious critique, as it creates the impression - at a glance - that the war is being waged in an unbiased manner, even when nothing could be further from the truth.

The dramatically different manner in which we, as a nation, responded to the crisis presented by drunk driving and the crisis caused by the emergence of crack cocaine speaks volumes about who we value, and who we view as disposable.
