Mounting a vigorous critique on existing approaches to transnational policing, this book lays out an argument situating transnational policing within contemporary transformations of the capitalist state and imperialism. Focusing on a particular case of regional police cooperation against sex trafficking in Southeast Europe, the study shows how contemporary dominant discourses on sex trafficking ultimately facilitate the implementation of new aggressive state strategies against migration and migrant workers and legitimise new police powers and operational capabilities at an international scale.
