Every four years the Summer Olympic Games fires the imagination of the largest and most diverse sport spectatorship and entices them in their hundreds of thousands to some of the First World’s most iconic and crowded cities. In addition, the ideological symbolism associated with the Olympic Games is rooted in Western, liberal democratic values and traditions. For those who do not share these ideals the Olympics represent something to stand against and, in extremity, disrupt and violate. In short, in a post-9/11 world, the Olympics provide a mouth-watering target for terrorists. Using themes of surveillance drawn form from Bentham and Foucault, this article analysis the nature of the terrorist threat and scale of the security operation designed to ensure the safety of the London 2012 Olympic Games. It concludes by considering the consequences of these measures on the city of London, particularly in terms of the civil liberties of its citizenry.
