Shoot-to-kill policy in Northern Ireland
During the Troubles in Northern Ireland, British security forces were accused by some of operating a "shoot-to-kill" policy, under which suspected paramilitary members were killed without an attempt being made to arrest them. This alleged policy was claimed to be most frequently directed against suspected members of Irish republican paramilitary organisations, such as the Provisional Irish Republican Army (IRA), Official Irish Republican Army (OIRA) and Irish National Liberation Army (INLA).
