Kent State protests
The Kent State protests of May 1970 began with violence and arson and ended in the deaths of four students.
During the demonstration on May 1, 1970, "a mix of bikers, students, and out-of town youths" [1] assaulted police with beer bottles.
The governor called out the National Guard.
On May 2, the ROTC was found ablaze. Protesters surrounded the building, cut a fire hose and assaulted fire fighters with "rocks and other objects". [2]
On May 3, protesters defying a curfew by the mayor were dispersed by guardsmen using tear gas.
On May 4, around 2,000 people gathered for a previously planned protest rally, despite the university's announcement of a ban or cancellation. When a police official ordered the crowd to disperse, his Jeep was "pelted with rocks" and one guardsman was injured. [3]
