A very good film. i recommend that you watch it to understand the politics of northwern ireland intertwined with the mainland during the troubles. It shows the danger of unchecked and unaccountable security services operating in an enviornment where they can get away with murder and become a law unto themselves, and where civil liberties are trampled upon in the name of a so-called war on terror. A warning for today. You cant help see similarities with todays situation whereby we have repressive legislation and the assasination of Jean Charles Demenezes. I am reminded of a quote from Wilhelm Reich that goes 'who guards the guards, who polices the police'.
