It looks like the whistle blower had a more difficult time than the war criminals. A sad story indeed.

My Lai massacre hero dies at 62
Hugh Thompson Jnr, a former US military helicopter pilot who helped stop one of the most infamous massacres of the Vietnam War has died, aged 62.
Mr Thompson and his crew came upon US troops killing civilians at the village of My Lai on 16 March 1968.
He put his helicopter down between the soldiers and villagers, ordering his men to shoot their fellow Americans if they attacked the civilians.
...................
A platoon commander, Lt William Calley, was later court-martialed and sentenced to life in prison for his role in the killings.
President Richard Nixon commuted his sentence to three years' house arrest.
.................................
Mr Thompson was shunned for years by fellow soldiers, received death threats, and was once told by a congressman that he was the only American who should be punished over My Lai.
