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.

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.

For the rest of their lives, [black men] can be denied the right to vote, automatically excluded from juries, and legally discriminated against in employment, housing, access to education and public benefits. So many of the old forms of discrimination that we supposedly left behind during the Jim Crow era are suddenly legal again once you've been branded a felon.

The education justice movement and the prison justice movement have been operating separately in many places as though they're in silos. But the reality is we're not going to provide meaningful education opportunities to poor kids, kids of color, until and unless we recognize that we're wasting trillions of dollars on a failed criminal justice system.

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.

Just providing information about how bad things are, or the statistics and data on incarceration by themselves, does lead to more depression and resignation and is not empowering. The information has to be presented in a way that's linked to the piece about encouraging students to think critically and creatively about how they might respond to injustice, and how young people have responded to injustice in the past.

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.
