Forty years ago, 504 unarmed Vietnamese civilians were killed by US soldiers. It became known as ‘The My Lai Massacre' and was covered up by the army for almost a year. In the second part of ‘The My Lai Tapes’, presented by Robert Hodierne, you can hear for the first time, the taped recordings of the US Army’s internal inquiry into the massacre.
