The Berkeley Free Speech Movement

California students staged a sit-in which became the model for student activism across the USA in the 1960s. It all started over who could, or could not, use a small strip of land outside Berkeley's front gates. Lynne Hollander Savio, who took part in the sit-in, remembers the mood of the time.
