U.S. Attorney General Eric Holder was the keynote speaker at the Brennan Center for Justice’s conference, “Shifting Law Enforcement Goals to Reduce Mass Incarceration.”

Holder noted that there are 4,800 fewer inmates in federal prisons than in September 2013, the first such decline since 1980. “Clearly, criminal justice reform is an idea whose time has come,” he said. “And thanks to a robust and growing national consensus—a consensus driven not by political ideology, but by the promising work that’s underway—we are bringing about a paradigm shift, and witnessing a historic sea change, in the way our nation approaches these issues.”
