attention of media and politics on their cause. The Irish Republican Army guerrillas of 1919–21 killed many RIC Police Intelligence officers during the Irish War of Independence. Michael Collins set up a special unit – the Squad – for this purpose, which had the effect of intimidating many policemen into resigning from the force. The Squad's activities peaked with the killing of 14 British agents in Dublin on Bloody Sunday in 1920. This tactic was used again by the Provisional IRA during the Troubles in Northern Ireland (1969–1998). Killing of RUC officers and assassination of RUC politicians was one of a number of methods used in the Provisional IRA campaign 1969–1997. The IRA also attempted to assassinate British Prime Minister Margaret Thatcher by bombing the Conservative Party Conference in a Brighton hotel. Loyalist paramilitaries retaliated by killing Catholics at random and assassinating Irish nationalist politicians. Basque terrorists ETA in Spain have assassinated many security and political figures since the late 1960s, notably Luis Carrero Blanco, 1st Duke of Carrero-Blanco Grandee of Spain, in 1973. Since the early 1990s, they have also targeted academics, journalists and local politicians who publicly disagreed with them. The Red Brigades in Italy carried out assassinations of political figures, as to a lesser extent, did the Red Army Faction in Germany in the 1970s and 1980s. In the Vietnam War, Communist insurgents routinely assassinated government officials and individual civilians deemed to offend or rival the revolutionary movement. Such attacks, along with widespread military activity by insurgent bands, almost brought the Diem regime to collapse before the U.S. intervention. Bank robberies Bank robberies have been used by insurgents and revolutionaries in order to fund their activities, for example the 1907 Tiflis bank robbery, using violence in excess of that needed to achieve the aims of the robberies helps contributes to a climate of fear. Group participation in atrocities As an initiation new recruits, especially forced ones, will be encouraged or forced to participate in atrocities, such as torture, rape and murder, unwilling recruits will be forced to do this against their own communities and families or be killed themselves. The goal of these atrocities is to divorce the new recruit from his or her previous life and bind them to the insurgency; criminals in their own eyes and in the eyes of society, such recruits will be led to believe that they cannot go back to their
