Media observers and readers of all stripes have been eager to cast doubts on Seymour Hersh’s account of what really happened when Osama Bin Laden was killed. The accuracy of his latest dispatch remains in question, but what’s not up for debate is the lasting impact of his reporting on the My Lai Massacre. Hersh’s Pulitzer-winning stories about U.S. soldiers who obliterated an entire village and killed hundreds of civilians transformed the way Americans saw the Vietnam War. The Newseum marks the 50th anniversary of the war with a new exhibition, “Reporting Vietnam,” which explains the conflict from a newsperson’s perspective. In addition to press passes, portable typewriters, and stories from people who were there, the exhibition focuses on how stories were reported when photos and video footage took nearly two days to reach New York from Saigon. It’ll make you thankful for instant file transfers and digital images. The exhibition is on view daily 9 a.m. to 5 p.m., to Sept. 12, 2016, at the Newseum, 555 Pennsylvania Ave. NW. $13.95–$22.95.
