In response to the advocacy of groups like Mothers Against Drunk Driving, most states adopted tougher laws to punish drunk driving. Numerous states now have some type of mandatory sentencing for this offense - typically two days in jail for a first offense and two to ten days for a second offense. Possession of a tiny amount of crack cocaine, on the other hand, was given a mandatory minimum sentence of five years in prison.

Mass incarceration is the most pressing racial justice issue of our time.

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.

Since the nation's founding, African Americans repeatedly have been controlled through institutions such as slavery and Jim Crow, which appear to die, but then are reborn in new form, tailored to the needs and constraints of the time.

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

For those interested in learning more about corporations and private individuals profiting from the caging of human beings, I highly recommend the book "Prison Profiteers: Who Makes Money From Mass Incarceration."

We must build a movement for education, not incarceration. A movement for jobs, not jails. A movement that will end all forms of discrimination against people released from prison - discrimination that denies them basic human rights to work, shelter and food.
