Hardtalk speaks to the British Muslim campaigner Moazzam Begg. He was detained at Guantanamo Bay between 2003 and 2005, and then last February he was held for seven months in a British prison. In October all terrorism-related charges against him were dropped and he walked free. He believes that current counter-terrorism measures are fuelling the very problems they are trying to tackle and are alienating and radicalising some Muslims. So how should Muslim communities work with the authorities to prevent the extremists carrying out attacks?(Photo: Moazzam Begg. Credit: Rob Stothard/Getty Images)
