“These are stories that are buried in history, and if we don’st tell them now they’sll never be known,” says Hank Klibanoff, creator/host of “Buried Truths” in this Peabody Conversation. Producers David Barasoain and Je-Anne Berry of WABE joined the veteran journalist to discuss the podcast, which was developed out of a class at Emory University. In it, students investigate cold cases that bring to life the South’s history of voter suppression and racial injustice that resonate today. The first season digs into the death of Isaiah Nixon, a black man gunned down outside his South Georgia home in 1948 for exercising his right to vote. Peabody Awards honored it “for forcing listeners to confront what previous generations had sought to repress.”
