Defenders of the system will counter by saying this drug war has been aimed at violent crime. But that is not the case. The overwhelming majority of people arrested in the drug war have been arrested for relatively minor, non-violent drug offenses.

Many people don't realize that financial incentives have been built into the drug war that guarantee that law enforcement will continue to arrest extraordinary numbers of people, particularly in poor communities of color, for minor drug offenses that get ignored on the other side of town.

All people make mistakes. All of us are sinners. All of us are criminals. All of us violate the law at some point in our lives. In fact, if the worst thing you have ever done is speed ten miles over the speed limit on the freeway, you have put yourself and others at more risk of harm than someone smoking marijuana in the privacy of his or her living room. Yet there are people in the United States serving life sentences for first-time drug offenses, something virtually unheard of anywhere else in the world.

Today there are more African-Americans under correctional control, in prison or jail, on probation or parole, than were enslaved in 1850, a decade before the Civil War began. There are millions of African-Americans now cycling in and out of prisons and jails or under correctional control or saddled with criminal records. In major American cities today, more than half of working-age African-American men either are under correctional control or are branded felons, and are thus subject to legalized discrimination for the rest of their lives.

The fact that more than half of the young black men in any large American city are currently under the control of the criminal justice system (or saddled with criminal records) is not - as many argue - just a symptom of poverty or poor choices, but rather evidence of a new racial caste system at work.

We're living in a time when so many of the civil rights and social justice organizations are run by lawyers and policy people who are often very disconnected from the communities they claim to represent.

My fear is that we will mistake the brand, the "resistance," for greater unity than actually exists and wind up settling for any Democrat the next time around. We have an opportunity right now to build much greater consensus about the need for a meaningful alternative and building a truly transformational movement, town by town, city by city, that has the potential to help birth truly revolutionary change in this country. That potential exists. We got a glimpse of it when such enthusiasm erupted over a democratic socialist Bernie Sanders running for president.
