From behind the stools, white men start taunting the mixed row of mostly black students who had the audacity to sit there. "He's so dark the whole room is darkened." "Nobody ain't gonna sit beside them dirty niggers." Those on the swiveling seats at the counter answer only with an unshakable look of dignity.  Frustrated, the men from behind start pushing and shoving. Still no response from those on the stools. Then they launch the attack: hurling obscenities, throwing milk shakes and live cigarette buts, grabbing and punching. Lenses capture the scene. The whole world watches in shock.
