Torture, the infliction of severe physical or psychological pain upon an individual to extract information or a confession, or as an illicit extrajudicial punishment, is prohibited by international law and is illegal in most countries. However, it is still used by many governments. The subject of this article is the use of torture since the adoption of the 1948 Universal Declaration of Human Rights (UDHR), which prohibited it.
Torture is widely practiced worldwide: Amnesty International received reports of torture or cruel, inhuman or degrading treatment or punishment in more than 150 countries during the four-year period from 1997 to 2001. These accusations concerned acts against political prisoners in 70 countries and other prisoners and detainees in more than 130 countries. State torture has been extensively documented and studied, often as part of efforts at collective memory and reconciliation in societies that have experienced a change in government. Surveys of torture survivors reveal that torture "is not aimed primarily at the extraction of information ... Its real aim is to break down the victim's personality and identity." When applied indiscriminately, torture is used as a tool of repression and deterrence against dissent and community empowerment.
While many states use torture, few wish to be described as doing so, either to their own citizens or to international bodies. So a variety of strategies are used to circumvent their legal and humanitarian duties, including plausible deniability, secret police, "need to know", denial that certain activities constitute torture, appeal to various laws (national or international), use of a jurisdictional argument, claim of "overriding need", the use of torture by proxy, and so on. Almost all regimes and governments engaging in torture (and other crimes against humanity) consistently deny engaging in it, in spite of overwhelming hearsay and physical evidence from the citizens they tortured. Through both denial and avoidance of prosecution, most people ordering or carrying out acts of torture do not face legal consequences for their actions. UN Special Rapporteur for the Commission on Human Rights, Sir Nigel Rodley, believes that "impunity continues to be the principal cause of the perpetuation and encouragement of human rights violations and, in particular, torture."
While states, particularly their prisons, law enforcement, military and intelligence apparatus, are major perpetrators of torture, many non-state actors also engage in it. These include paramilitaries and guerrillas, criminal actors such as organized crime syndicates and kidnappers.
A recent approach to interrogations has been to use techniques such as waterboarding, sexual humiliation and sexual abuse, and dogs to intimidate or pressure prisoners in a manner claimed to be legal under national or international law. Electric shock techniques such as the use of stun belts and tasers have been considered appropriate provided that they are used to "control" prisoners or suspects, even non-violent ones, rather than to extract information. These techniques have been widely criticized as torture.
Technology
Methods of torture are often quite crude, a number of new technologies of control have been used by torturers in recent years. The Brazilian government devised a number of new electrical and mechanical means of torture during the military dictatorship from 1964 to 1985, and proceeded to train military officials from other right-wing Latin American countries in their techniques. One is the use of tasers and electro-shock devices now widely sold to prison authorities around the world. Minor refinements of ancient techniques—including tearing out fingernails and toenails with iron tools, burning the soles of the feet with clothes irons, and probing between the toes with electric wood-burning pencils—are also widely applied. Some African nations employ an iron foot-squeezing device patterned after the medieval French boot.
