Anderson Cooper had a realization about a hostage during a live interview with his parents

CNN’s Anderson Cooper speaks with the parents of Hersh Goldberg-Polin, a 23-year-old American who was wounded and kidnapped by Hamas at an Israeli music festival. Cooper discovered he had unknowingly obtained footage from an Israeli soldier of their son being put into a truck by Hamas militants after he interviewed Goldberg-Polin’s parents the first time.
