"I saw a child fall down. Under a shower of bullets I rushed forward and went for the picture. It had been a peaceful march, the children were told to disperse, they started singing Nkosi Sikelele. The police were ordered to shoot." These are the words of Sam Nzima, whose famous photograph of a dying Hector Pieterson encapsulated the anger and tragedy of a day that, 30 years ago, changed the course of SA history.
