Four students were fatally shot by troops from the National Guard on May 4, 1970. The shootings happened as the United States was winding down its participation in the civil war in the small country of Vietnam. The incident divided the country at the time, and is still a subject of conflicting interpretations. This activity is a brief reading that summarizes the events, the areas of certainty, and the areas of differing interpretations. Readers are asked to imagine a conversation, years later, between a former student and a former Guardsman.
