The bigger picture is that over the last 30 years, we have spent $1 trillion waging a drug war that has failed in any meaningful way to reduce drug addiction or abuse, and yet has siphoned an enormous amount of resources away from other public services, especially education.

Millions of people are unable to vote due to felony convictions with the highest rates among black men. People in prison are denied the right to vote in 48 states, and while we accept that as normal in the United States, in other western democracies people in prison do have the right to vote.

In many large urban areas, the majority of working age African American men now have criminal records and are thus subject to legalized discrimination for the rest of their lives. It is viewed as "normal" in ghetto communities to go to prison or jail.

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.

About 70% of those released from prison return within a few years, and the majority of those who return in some states do so in a matter of months because the challenges associated with mere survival on the outside are so immense.

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

Most Americans violate drug laws in their lifetime, but the enemy in this war has been racially defined. Not by accident, the drug war has been waged almost exclusively in poor communities of color, even though studies have consistently shown - for decades - the people of color are no more likely to use or sell illegal drugs than whites.
