Transnational crime and security are key modalities of governance in a globalizing world. World-wide, there is a tendency to treat every imaginable source of harm as a potential source of insecurity, and therefore as a crime. The catastrophic imagination is fueled by the precautionary logics of a world system troubled by systemic risk. As these logics become pervasive, security measures are invoked in an effort to control the imagined sources of harm, and the consequences are not always clear-cut. Further, the terminology of transnational crime, threat, risk and (in)security (and the phenomena to which they refer) is substantively deterritorialized, raising further theoretical and practical difficulties. Research and scholarship concerning these issues touches upon crucial features of the world system. This series offers wide inter-disciplinary scope for scholarship exploring these central aspects of global governance and governance globally.
