Since the early 1970s, extrajudicial punishment attacks have been carried out by Ulster loyalist and Irish republican paramilitary groups in Northern Ireland. Attacks can range from a warning or expulsion from Northern Ireland, backed up by the threat of violence, to severe beatings that leave victims in hospital and shootings in the limbs (such as kneecapping). The cause of the attacks is disputed; proposed explanations include the breakdown of order as a result of the Northern Ireland conflict (c. 1970–1998), ideological opposition to British law enforcement (in the case of republicans), and the ineffectiveness of police to prevent crime.
Since reporting began in 1973, more than 6,106 shootings and beatings have been reported to the police, leading to at least 115 deaths. The official figures are an underestimate because many attacks are not reported. Most victims are young men and boys under the age of thirty years, whom their attackers claim are responsible for criminal or antisocial behaviour. Despite attempts to put an end to the practice, according to researcher Sharon Mallon in a 2017 policy briefing, "paramilitaries are continuing to operate an informal criminal justice system, with a degree of political and legal impunity".[1]
