Files obtained by the website Wikileaks have revealed that the US believed many of those held at Guantanamo Bay were innocent or only low-level operatives. The files, published in US and European newspapers, are assessments of all 780 people ever held at the facility. They show that about 220 were classed as dangerous terrorists, but 150 were innocent Afghans and Pakistanis. The Detainee Assessment Briefs (DABs) ... give little information on the allegations of harsh treatment and interrogation techniques at the camp. But the files show that US military analysts considered only 220 of those ever detained at Guantanamo to be dangerous extremists. Another 380 detainees were deemed to be low-ranking guerrillas. At least 150 people were revealed to be innocent Afghans or Pakistanis - including drivers, farmers and chefs - rounded up during intelligence gathering operations in the aftermath of 9/11. The detainees were then held for years owing to mistaken identity or because they were in the wrong place at the wrong time, the memos say. In many cases, US commanders concluded there was "no reason recorded for transfer".
