Tony Long was the best 'shot' the Met ever had. Under the codename 'Echo 7,' he was 'licensed to kill' bringing down scores of targets, sometimes with deadly force. In 1985 he opened fire on a suspect to save a four-year-old girl whose mother had been stabbed to death by her assailant. Two years later he was involved in another high profile shooting while confronting three armed criminals. On both occasions Tony was commended by the Metropolitan Police Commissioner. But in the spring of 2005, coming face to face with suspected drug dealer and armed robber Azelle Rodney, a volley of point blank shots would bring his career crashing to an end, tarnish his reputation and leave him fighting a murder charge and possible life sentence. This book charts his controversial career from rookie seventies beat cop to Long's command of SO19 - the Met's most elite specialist firearms unit.
