Vietnam Civilian Killings

After the My Lai massacre (killing of around 400-500 innocent civilians in Vietnam by U.S. army troops), the U.S. government established a group to investigate other war crimes like this occurring in Vietnam under the Vietnam War Crimes Working group. They found 28 massacres of equal or greater magnitude than My Lai that the public was unaware of, so literally thousands of innocent people were killed by the U.S soldiers. The information has since been reclassified, but there were several journal articles on it when it was first released.
