was released after the prosecution announced that they would be offering no evidence due to documents having come into their possession showing that MI5 had been aware of, and had consented to, Begg's travels to Syria. West Midlands Police said "new evidence had come to light" and immediately following the verdict, its assistant chief constable said the police fully accepted that Moazzam Begg was an innocent man. A CPS spokesperson said 'If we had been made aware of all of this information at the time of charging, we would not have charged'. Open letter to President Biden On 29 January 2021 the New York Review of Books published an open letter from Begg, and six other Guantanamo detainees, to newly inaugurated American President Biden, appealing to him to close the detention camp. Documentary appearances Begg was among those interviewed in the 2007 documentary Taxi to the Dark Side about the killing of an Afghan taxi driver at Bagram detention centre. The film, which was directed by American filmmaker Alex Gibney, won the 2007 Academy Award for "Best Documentary Feature". The documentary was also shown as part of the international Why Democracy? documentary series. Begg is the subject of an extended interview in The Confession (2016), discussing his life prior to his incarceration in Guantánamo Bay, his incarceration, and subsequent life. It was given four stars by the Guardian, who described Begg's "principled, consistent testimony" having a "rare gravity and profound moral force". This documentary has also been shown in the BBC Storyville documentary series, under the title Moazzam Begg: Living the War on Terror. Begg is interviewed in the 2009 documentary Outside the Law: Stories from Guantanamo, co-directed by Andy Worthington and Polly Nash. The film focuses on the cases of Begg and other UK detainees with comments by lawyers Clive Stafford Smith, Gareth Peirce and Tom Wilner. In 2006, Begg was interviewed in the video 21st Century CrUSAders, saying that the War on Terrorism is really akin to a war against Islam. According to Gareth Peirce, possession of this film has been offered in British courts as evidence of radicalisation. Representation in play Begg, and his father Azmat, both feature as characters in a play written by Victoria Brittain and Gillian Slovo, entitled Guantanamo: Honor Bound to Defend Freedom, which opened in 2004 at the Tricycle Theatre before transferring to the New Ambassadors Theatre in London's West End.
