In the aftermath of the American Invasion of Cambodia on April 30, 1970, four students were killed at Kent State University on May 4, 1970 in Ohio,... as well as two students at Jackson State College in Mississippi on May 14/15. More than 450 university, college and high school campuses across the country were shut down by student strikes and both violent and non-violent protests that involved more than 4 million students.

On May 8, ten days after Nixon announced the Cambodian invasion , 100,000 protesters gathered in Washington and another 150,000 in San Francisco. Nationwide, students turned their anger on what was often the nearest military facility—college and university Reserve Officers' Training Corps offices.
