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 New Jim Crow: Mass Incarceration in the Age of Colorblindness.

One study conducted in Washington, D.C. indicated that 3 out of 4 black men, and nearly all those living in the poorest neighborhoods could expect to find themselves behind bars at some point in their life.

Nationwide, 1 in 3 black men can expect to serve time behind bars, but the rates are far higher in segregated and impoverished black communities.

The wave of punitiveness that washed over the United States with the rise of the drug war and the get tough movement really flooded our schools. Schools, caught up in this maelstrom, began viewing children as criminals or suspects, rather than as young people with an enormous amount of potential struggling in their own ways and their own difficult context to make it and hopefully thrive. We began viewing the youth in schools as potential violators rather than as children needing our guidance.

Middle-class white children, children of privilege, are afforded the opportunity to make a lot of mistakes and still go on to college, still dream big dreams. But for kids who are born in the ghetto in the era of mass incarceration, the system is designed in such a way that it traps them, often for life.

In my view, the critical questions in this era of mass incarceration are: What disturbs us? What seems contrary to expectation? Who do we really care about?
