of conditions in Nazi Germany or Communist Russia". Despite this, he said that in order for abuse to remain legal, Mau Mau suspects must be beaten mainly on their upper body, "vulnerable parts of the body should not be struck, particularly the spleen, liver or kidneys", and it was important that "those who administer violence ... should remain collected, balanced and dispassionate". He also agreed to draft legislation that sanctioned beatings, as long as the abuse was kept secret, and reminded the governor that "If we are going to sin," he wrote, "we must sin quietly." Northern Ireland During the Troubles, an ethno-nationalist conflict in Northern Ireland, there were instances of British security forces, including the British Army and the Royal Ulster Constabulary (RUC), using torture on suspected Irish Republican Army (IRA) members. Former RUC interrogators who were active during the Troubles claimed that waterboarding, among other forms of torture, were systematically used against suspected IRA members in police custody. In 1971, as part of Operation Demetrius, fourteen arrested men were subjected to a programme of "deep interrogation" at a secret interrogation centre. The interrogation methods involved sensory deprivation and were referred to as the "Five Techniques". The European Court of Human Rights defined them as wall-standing, hooding, subjection to noise, deprivation of sleep, and deprivation of food and drink. For seven days, when not being interrogated, the detainees were kept hooded and handcuffed in a cold cell and subjected to a continuous loud hissing noise. Here they were forced to stand in a stress position for many hours and were deprived of sleep, food and drink. They were also repeatedly beaten, and some reported being kicked in the genitals, having their heads banged against walls and being threatened with injections. The effect was severe pain, severe physical and mental exhaustion, severe anxiety, depression, hallucinations, disorientation and repeated loss of consciousness. The fourteen so-called "Hooded Men" were the only detainees subjected to all Five Techniques together. Some other detainees were subjected to at least one of the Five Techniques, along with other interrogation methods. These allegedly included waterboarding, electric shocks, burning with matches and candles, forcing internees to stand over hot electric fires while beating them, beating and squeezing of the genitals, inserting objects into the anus, injections, whipping the soles of the feet, and psychological abuse such as Russian roulette.
