The British government has deported a former Guantanamo guard who was scheduled to address a meeting of Cageprisoners, a human rights organization that tries raise awareness of the plight of the prisoners at Guantanamo Bay. The former guard, Terry Holdbrooks, has become an outspoken critic of the US government over the treatment of prisoners at Guantánamo. Holdbrooks was denied entry into Britain after landing at Heathrow airport on Saturday. Holdbrooks told the Observer newspaper of London that he had also been detained and questioned by US airport officials on Thursday, as he attempted to complete the first stage of his journey.
