Answer:
William Calley was convicted and sentenced to life imprisonment for the murder of twenty-two civilians at My Lai, but was paroled after serving three years under house arrest at a military base.
Step-by-step explanation:
William Laws Calley, Jr. is an officer of the United States Army who participated in the Vietnam War. He was found guilty of ordering the My Lai Massacre on March 16, 1968. Three years later he was pardoned by Nixon.
Reports about his performance published after My Lai describe him as a normal soldier. Later, as the investigation progressed, his image worsened. Several members of his platoon told Army investigators that he lacked common sense and that he was unable to use a map or a compass. Calley was charged on September 5, 1969, with six counts of premeditated murder, and was found guilty. Richard Nixon commuted the sentence 3 years later.
