In 1968 , the Vietnam War Crimes Working Group ( VWCWG ) was established by the Pentagon task force set up in the wake of the My Lai Massacre , to attempt to ascertain the veracity of emerging claims of war crimes by U.S. armed forces in Vietnam , during the Vietnam War period . A probable war crime that was neither investigated nor brought to charge was the Thuy Bo massacre , while the Son Thang massacre warranted investigation , and its perpetrators faced court martial and served less than a year in prison
