in it, but the proportion was higher than the regular British Army, the RUC and the civilian population. During the 1970s, the Glenanne gang—a secret alliance of loyalist militants, British soldiers and RUC officers—carried out a string of gun and bomb attacks against nationalists in an area of Northern Ireland known as the "murder triangle". It also carried out some attacks in the Republic, killing about 120 people in total, mostly uninvolved civilians. The Cassel Report investigated 76 murders attributed to the group and found evidence that soldiers and policemen were involved in 74 of those. One member, RUC officer John Weir, claimed his superiors knew of the collusion but allowed it to continue. The Cassel Report also said some senior officers knew of the crimes but did nothing to prevent, investigate or punish. Attacks attributed to the group include the Dublin and Monaghan bombings (1974), the Miami Showband killings (1975) and the Reavey and O'Dowd killings (1976). The Stevens Inquiries found that elements of the security forces had used loyalists as "proxies", who, via, double-agents and informers, had helped loyalist groups to kill targeted individuals, usually suspected republicans but civilians were also killed, intentionally and otherwise. The inquiries concluded this had intensified and prolonged the conflict. The British Army's Force Research Unit (FRU) was the main agency involved. Brian Nelson, the UDA's chief 'intelligence officer', was a FRU agent. Through Nelson, FRU helped loyalists target people for assassination. FRU commanders say they helped loyalists target only suspected or known republican activists and prevented the killing of civilians. The Inquiries found evidence only two lives were saved and that Nelson/FRU was responsible for at least 30 murders and many other attacks – many on civilians. One victim was solicitor Pat Finucane. Nelson also supervised the shipping of weapons to loyalists in 1988. From 1992 to 1994, loyalists were responsible for more deaths than republicans, partly due to FRU. Members of the security forces tried to obstruct the Stevens investigation. A Police Ombudsman report from 2007 revealed that UVF members had been allowed to commit a string of terrorist offences, including murder, while working as informers for RUC Special Branch. It found that Special Branch had given informers immunity by ensuring they were not caught or convicted, and blocking weapons searches. Ombudsman Nuala O'Loan concluded that this had led to "hundreds" of deaths and said senior British Government officials pressured her
