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 United States does have the highest rate of incarceration in the world dwarfing the rates of even highly repressive regimes like Russia, China or Iran. This reflects a radical shift in criminal justice policy, a stunning development that virtually no one - not even the best criminologists - predicted forty years ago.

The United States imprisons a larger percentage of its black population than South Africa did at the height of apartheid. In Washington, D.C., our nation’s capitol, it is estimated that three out of four young black men (and nearly all those in the poorest neighborhoods) can expect to serve time in prison.

Public housing projects as well as private landlords are free to deny housing to people with criminal records. In fact, you don't even have to be convicted. You can be denied housing - or your family evicted - just based on an arrest.

By waging the drug war and "getting tough" almost exclusively in the 'hood, we've managed to create a vast new racial undercaste in an astonishingly short period of time.

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.

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