 In an interview with "The Guardian" before his own death, one of the killers, John Kennaway said the security inside the Maze was "a joke".He claimed the weapons had been smuggled to McWilliams and Glennon inside nappies.He added that as soon as the "screws" [prison officers] had seen the INLA men on A wing's roof, they assumed the men were staging an escape and sounded the alarm system.
