[1]  [DOC] William Laws Calley Jr. (born June 8, 1943) is a former United States Army officer convicted by court-martial of murdering 22 unarmed South Vietnamese civilians in the My Lai Massacre on March 16, 1968, during the Vietnam War. While not technically exonerated, after three and a half years of house arrest, Calley was released after a ruling by federal judge J. Robert Elliott who found that Calley's trial had been prejudiced by pre-trial publicity, denial of subpoenas of certain defense witnesses, refusal of the United States House of Representatives to release testimony taken in executive session of its My Lai investigation, and inadequate notice of the charges. His initial conviction faced widespread public opposition both due to the campaign circumstances of civilian embedded Viet Cong, and due to Calley being singled out as the sole convicted officer in relation to the massacre. [END]
