"My Lai, And Its Omens" by Seymour M. Hersh, The New York Times, March 16, 1998

This article was written thirty years after the Vietnam War's My Lai massacre, where American soldiers killed hundreds of Vietnamese civilians. It explains how the massacre was part of a larger problem of misconduct during the war. An earlier Army report had already warned that U.S. troops did not understand or follow the Geneva Conventions, which set rules for the humane treatment of civilians and prisoners.
