The Columbia Journalism Review recently invited journalists, academics, and experts to convene at a conference called "FaultLines: Democracy." In this episode, taped at the FaultLines conference, Masha Gessen, of The New Yorker; Jodie Ginseberg, president of the Committee to Protect Journalists; and Sheila Coronel, an expert in global investigative journalism, discuss how authoritarian regimes are erasing traces of the past and recasting history in dangerous ways.
