After spending two nights locked up and embedded inside the notorious Louisiana State Penitentiary, the largest maximum security prison in America, for a special one-hour Dateline NBC, “Life Inside,” Lester Holt moderated an unprecedented town hall from a maximum security prison at New York’s Sing Sing Correctional Facility. The town hall explores the criminal justice and prison reform debate. The audience includes current inmates, as well as artist and activist John Legend, former U.S. Attorney General Loretta Lynch, and Bryan Stevenson, civil rights attorney and founder of the Equal Justice Initiative.
