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.

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.

I do believe that something akin to a racial caste system is alive and well in America.

If we continue to tell ourselves the popular myths about racial progress or, worse yet, if we say to ourselves that the problem of mass incarceration is just too big, too daunting for us to do anything about and that we should instead direct our energies to battles that might be more easily won, history will judge us harshly. A human rights nightmare is occurring on our watch.

I think that we need to begin talking about what does it mean to create these safe spaces in our communities, to begin welcoming one another into our homes and into our communities when they're returning home from prison, people who are on the streets. We need to begin doing the work in our own communities of creating the kind of democracy that we would like to see on a larger scale.

A new race-neutral language was developed for appealing to old racist sentiments, a language accompanied by a political movement that succeeded in putting the vast majority of backs back in their place. Proponents of racial hierarchy found they could install a new racial caste system without violating the law or the new limits of acceptable political discourse, by demanding 'law and order' rather than 'segregation forever'.

Plenty of drug dealing does happen in the 'hood, but it happens everywhere else in America as well. In fact, some studies suggest that where significant differences in the data can be found, white youth are more likely to engage in illegal drug dealing than black youth.
