The Report of The President's Commission on Camps Unrest"On April 30, 1970, President Nixon announced that American and South Vietnamese forces were moving against enemy sanctuaries in Cambodia. Minutes after this announcement, student-organized protest demonstrations were under way at Princeton and Oberlin College. Within a few days, strikes and other protests had taken place at scores of colleges and universities throughout the country.
The expanding wave of strikes brought with it some serious disturbances. One of these was at Kent State University in Ohio, and approximately 750 Ohio National Guardsmen were sent to quell the disorders there.
On May 2, the ROTC building at Kent State was set afire. On May 4, Kent State students congregated on the university Commons and defied an order by the Guard to disperse. Guardsmen proceeded to disperse the crowd. The students then began to taunt Guard units and to throw rocks. The guardsmen fired tear gas into the crowd, and then some fired their weapons. Four students were killed, and nine were wounded."
