lThe emergence of a security discipline in the post 9-11 discourse of US security organisations

This paper explores two views of the changes that have occurred in the U.S. security services as a result of their post 9/11 reform. The first is Bigo's suggestion that agencies worldwide have become enmeshed in shared activity so as to constitute a new 'field of (in) security'. A second, novel perspective is that the security services have developed many of the characteristics of a discipline or 'discursive formation', constructing intelligence both as a form of expertly constituted knowledge and as the basis for a new type of professional, disciplinary power. The investigation combines corpus techniques with other discourse analysis procedures to examine a corpus of public-facing texts generated by the U.S. security agencies. The investigation aims to synthesise evidence consistent with both views of the security services' recent historical change; that features of their discourse signal their emergence simultaneously as a new field and discursive formation.
