National Guard kill four students at Kent State

In Kent, Ohio, 28 National Guardsmen fire their weapons at a group of antiwar demonstrators on the Kent State University campus, killing four students, wounding eight, and permanently paralysing another. Two days earlier, the National Guard troops were called to Kent to suppress students rioting in protest of the Vietnam War and the U.S. invasion of Cambodia. The next day, scattered protests were dispersed by tear gas, and on 4 May class resumed at Kent State University.

By noon that day, despite a ban on rallies, some 2,000 people had assembled on the campus. National Guard troops arrived and ordered the crowd to disperse, fired tear gas, and advanced against the students with bayonets fixed on their rifles. Some of the protesters, refusing to yield, responded by throwing rocks and verbally taunting the troops. Minutes later, without firing a warning shot, the Guardsmen discharged more than 60 rounds toward a group of demonstrators in a nearby parking lot, killing four and wounding nine.

The closest casualty was 20 yards away, and the farthest was almost 250 yards away. After a period of disbelief, shock, and attempts at first aid, angry students gathered on a nearby slope and were again ordered to move by the Guardsmen. Faculty members were able to convince the group to disperse, and further bloodshed was prevented. In 1974, at the end of a criminal investigation into the Kent State incident, a federal court dropped all charges levied against eight Ohio National Guardsmen for their role in the students' deaths.
