Kent State University incident
On May 4th, 1970, four students attending Kent State University were shot and killed by National Guardsmen. The situation in which this shooting transpired was a demonstration by the Kent State students against President Richard Nixon's expansion of the Vietnam War into Cambodia. The students had performed such demonstrations the three previous nights, and nearly 70 arrests were made by the guardsmen, called in after the Army Reserve Officers Training Corps building was burned. On the evening of May 4th, the National Guard ordered crowds of protestors to disperse and threw tear gas canisters. Students threw rocks at the soldiers, who claimed to hear a rifle fired at them. Several shots from the soldiers ensued, leaving four students, two male and two female, dead. This news story prompted more disdain for the ever-expanding war and anger toward the government.
