Angela Davis’ appearance at Columbia College’s Getz Theater April 30 was book ended by standing ovations. As she strode out onto the stage, the intergenerational audience that had been buzzing in anticipation rose as one and clapped wildly. In a mark of her status as a living cultural icon, some in the audience were sporting T-shirts with the famous image of her from the 1970s, when Davis was wanted and eventually jailed by the FBI, sparking an international “Free Angela” campaign that led to her eventual release.
