Excerpts from Books and Wikipedia
"It started as a demonstration against the 1950 Past Laws, which required nonwhites to carry identity cards and forbade them from spending the nights in a 'white' area, even if it was their place of work. . . . At the height of the protest, a crowd of several thousand surrounded the local police station. . . . Yet the police still decided to open fire, killing 69 and wounding almost 200. . . . Instead, on April 1, the United Nations Security Council called for South Africa to end racial segregation." [Furtado: 1001 Days]
