Private prison companies are now listed on the New York Stock exchange and are doing quite well in a time of economic recession (and depression in some communities). But that's just the tip of the iceberg.

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.

People charged with drug offenses, though, are typically poor people of color. They are routinely charged with felonies and sent to prison.

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.

It's important to teach students about the reality of the system, that it is in fact the case that they are being targeted unfairly, that the rules have been set up in a way that authorize unfair treatment of them, and how difficult it is to challenge these laws in the courts. We need to teach them how our politics have changed in recent years, how there has been, in fact, a backlash. But we need to couple that information with stories of how people in the past have challenged these kinds of injustices, and the role that youth have played historically in those struggles.

Yet far from putting any meaningful constraints on law enforcement in this war, the U.S. Supreme Court has given the police license to stop and search just about anyone, in any public place, without a shred of evidence of criminal activity, and it has also closed the courthouse doors to claims of racial bias at every stage of the judicial process from stops and searches to plea bargaining and sentencing.
