PBS’s Independent Lens' documentary series, “Philly D.A.”, takes viewers into the office of Philadelphia District Attorney Larry Krasner as he and his team work to transform the criminal justice system from the inside. In the vein of "Knock Down the House" and "Flint Town," “Philly D.A.” brings viewers behind the scenes, giving them a vivid, firsthand look at a District Attorney’s office attempting to transform the future of mass incarceration, the culture of prosecution and the fundamental meaning of justice.

GBH Contributor Sue O'Connell chats with filmmakers Ted Passon and Nicole Salazar about the making of the series and how District Attorneys across the country are working to transform the criminal justice system.
