CIA Used Gun, Drill in Interrogation

There are two reasons.

Charlie Company had received erroneous data prior to entering the village and had been told that the Viet Cong had gotten through to the people and those people left were in league with the North. Those unfamiliar with Vietnam War may consider that silly but often people of these ages old and young participated in deadly acts.

It seems to always be overlooked that the day before this occurred Charlie Company got caught in a mine field. Every time a soldier moved they would be blown to bits.

These same soldiers were in shock when they entered the village of My Lai.

Of course it is nice of Calley to apologize. Although, it is my opinion it is for his benefit.

The My Lai Massacre was a terrible marker of the questionable Vietnam War.

However, while Calley's apology is a gentile act, it in no way lessens the historic effect of the massacre and neither does it allow for the explanation of what really happened.
