No scholar, policy-maker or practitioner of policing could be taken seriously who did not acknowledge and take into account the radical transformation which privatization and pluralisation has brought to the field of policing (Jones & Newburn, 2006). Nevertheless, this transformation is largely influenced by the nature of the policing tradition in each nation state. To illustrate this argument a descriptive analysis of plural policing in the metropolis Paris is presented. Being part of the Napoleonic policing tradition in France, Paris takes up a unique political and administrative position which affects its security architecture. It stands out as the most developed example of centralisation and the State’s wish to control its citizens. Despite the observed pluralisation in terms of privatization; Paris is still a ‘state’ in the state. Its Napoleonic tradition largely ‘suppresses’ civil non-commercial initiatives and influences the development of municipal police forces and other public uniformed surveillance agencies in Paris.
