News of the death of William Calley arrived this week. It turns out that the one-time second lieutenant, who in 1968 led the massacre of Vietnamese at the village of My Lai in Vietnam, died in obscurity in April. He was 80 years old when he left this mortal coil at a hospice at Gainesville, Florida. The death was reported this week by the Post newspaper at Washington. The news offers a moment for reflection for the Vietnam generation.
