We must muster the courage, we must find the will, we must do what is necessary to build a truly transformative movement that will end the history and cycle of caste in America.

What has changed since the collapse of Jim Crow has less to do with the basic structure of our society than with the language we use to justify it. In the era of colorblindness, it is no longer socially permissible to use race, explicitly, as a justification for discrimination, exclusion, and social contempt. So we don't. Rather than rely on race, we use our criminal justice system to label people of color "criminals" and then engage in all the practices we supposedly left behind.

Once you're labeled a felon, the old forms of discrimination - employment discrimination, housing discrimination, denial of the right to vote, denial of educational opportunity, denial of food stamps and other public benefits, and exclusion from jury service - are suddenly legal. As a criminal, you have scarcely more rights, and largely less respect, than a black man living in Alabama at the height of Jim Crow. We have not ended racial caste in America; we have merely redesigned it.

The fate of millions of people—indeed the future of the black community itself—may depend on the willingness of those who care about racial justice to re-examine their basic assumptions about the role of the criminal justice system in our society.

People charged with drug offenses, though, are typically poor people of color. They are routinely charged with felonies and sent to prison.

I think it's important to encourage young people to tell their own stories and to speak openly about their own experiences with the criminal justice system and the experiences of their family. We need to ensure that the classroom environment is a supportive one so that the shame and stigma can be dispelled.

Mandatory minimum sentences give no discretion to judges about the amount of time that the person should receive once a guilty verdict is rendered. Harsh mandatory minimum sentences for drug offenses were passed by Congress in the 1980s as part of the war on drugs and the "get tough" movement, sentences that have helped to fuel our nation's prison boom and have also greatly aggravated racial disparities, particularly in the application of mandatory minimum sentences for crack cocaine.
