Standing atop the crushed roof of a campus police car, a University of California student asks Cal students to identify themselves during the third day of Free Speech Movement demonstrations at Berkeley, Calif., Oct. 2, 1964.
Free Speech Movement protesters at the University of California Berkeley, were hauled off in handcuffs. Friday, Oct. 8, 2004, they were welcomed back with open arms. The protest was against a ban on political activities on campus.
The Free Speech Movement is credited as being the first on-campus protest that set the mold for college protests for the rest of the 1960s.
Mario Savio, facing camera foreground, leader of the so-called Free Speech Movement at the University of California, gathered a crowd of some 3,000 students in front of Sproul Hall on the Berkeley campus on Dec. 2, 1964.
Savio, 21, told the crowd that sit-in demonstrators planned to occupy the second floor of Sproul Hall until the administration dropped disciplinary action against four free speech leaders.
