Abstract
In this article the author examines the broadest regulatory implications of the flow of policing authority from the state towards the supranational EU. The cultural and constitutional context of state and supranational policing are compared, and it is argued that supranational policing, while suffering from various governance problems which are not typically encountered by the state police, nevertheless holds out the prospect of overcoming some deep-rooted paradoxes of state policing. The challenges of institutional design and political mobilization which are faced by supranational policing in dealing with difficulties and exploiting opportunities associated with the legitimacy of its new mandate are assessed.
