High value detainee

Extrajudicial prisoners of the United States, in the context of the early twenty-first century War on Terrorism, refers to foreign nationals the United States detains outside of the legal process required within United States legal jurisdiction. In this context, the U.S. government is maintaining torture centers, called black sites, operated by both known and secret intelligence agencies. Such black sites were later confirmed by reports from journalists, investigations, and from men who had been imprisoned and tortured there, and later released after being tortured until the CIA was comfortable they had done nothing wrong, and had nothing to hide.

Of these prisoners being held by the U.S., some were suspected of being from the senior ranks of al Qaeda, referred to in U.S. military terms as "high value detainees." According to the Swiss senator Dick Marty's reports on Secret Detentions and Illegal Transfers of Detainees involving Council of Europe Member States, about a hundred persons had been kidnapped by the CIA on European territory and subsequently rendered to countries where they were tortured.

Former Secretary of Defense, Donald Rumsfeld, had described the men detained in Camp Delta at Guantánamo Bay, Cuba, as "the worst of the worst.", despite concerns about the mental capacity of several of the detainees. But, before September 2006, many of those detainees suspected of having the highest intelligence value were not detained at Guantanamo, but were held at CIA's black sites in Eastern Europe and other countries, including Afghanistan.
