On May 4, 1970 the Ohio National Guard opened fire on unarmed students protesting America´s invasion of Cambodia. Four students were killed and nine were wounded. The incident triggered national outrage in a country already divided over the Vietnam War. In the days that followed more than four million students rose up in dissent across 900 campuses, generating the only nationwide student protest in U.S. history. Fearing civil unrest, President Nixon was taken to Camp David for his protection. The Kent State shootings have never been thoroughly examined. Forty years later, family members of those killed have initiated the Kent State Truth Tribunal to preserve and honor the stories of those whose lives have been touched by this tragedy. The Truth Tribunal is generating the only comprehensive historical record and live archive of the Kent State massacre.
