More than four decades since President Nixon declared “a war on drugs”, judges, legislators, policy makers, academics and other gathered at a conference in Chicago last week to discuss the current status of drug sentencing legislation and policy. We talk with conference moderator Ruben Castillo, Chief Judge of the U.S. District Court of Northern Illinois. Castillo is the former Vice-Chair of the Sentencing Commission which establishes federal sentencing and policies. (Photo: Flickr/abodftyh)
