On 4 May 1919, in Beijing, some 3,000 students demonstrated outside the home of the Minister of Communications. After pelting its residents with eggs, they broke in, trashed the building and then torched it. This violent, but rather small scale, incident turned out to be one of the key turning points in 20th Century history, in many ways the real beginning of the Chinese Revolution.
On 5 October 1968, the Royal Ulster Constabulary (RUC) savagely beat a peaceful civil rights march off the streets of Derry. This police riot was flashed over television screens throughout Ireland and Britain that very evening. Among the defenceless marchers was Westminster MP Gerry Fitt, with blood streaming down his face after being truncheoned. Some 96 people needed hospital treatment.
