According to Reda Hassaine, an Algerian mole working against Islamist extremists in London for MI5, Britain’s domestic intelligence service, his handler tells him MI5 is powerless against Algerian extremists in London. Hassaine will say: “He [the handler] certainly never cared about what I cared most about, that hundreds of people were being killed in Algeria and that many of the killers and the organizers of the massacres had escaped to London. ‘Oh, what can we do?’ he would say. ‘We can’t stop them, there is nothing we can do.’” [O’Neill and McGrory, 2006, pp. 139]
