As a former federal prosecutor in Washington, D.C., Paul Butler once worked to put people in prison. Now, he has come to believe that prisons should be abolished. In this episode of the Modern Law Library, Butler speaks with the ABA Journal's Lee Rawles about the racial inequities built into the system; his advice for young black men interacting with the police; and his view that radical re-imagining, rather than incremental reform, is the only way to fully address the harm done to civil rights by the criminal justice system.
