Demonstrators face off with police after tear gas was fired at protesters reacting to the shooting of Michael Brown in Ferguson, MissouriYou probably have heard of the Kent State shootings: on May 4, 1970, the Ohio National Guard opened fire on student protesters at Kent State University. During those 13 seconds of gunfire, four students were killed and nine were wounded, one of whom was permanently paralyzed. The shock and outcry resulted in a nationwide strike of 4 million students that closed more than 450 campuses. Five days after the shooting, 100,000 protestors gathered in Washington, D.C. And the nation’s youth was energetically mobilized to end the Vietnam War, racism, sexism, and mindless faith in the political establishment. MORE
