Stephen Flynn did a series for NPR this week called The Edge of Disaster that would be worth a listen. One of the themes is that reduced attention to population security has also increased vulnerability of vital systems, as this nice diary from DailyKos points out in relation to avian flu.
COLLABORATORY: VITAL SYSTEMS SECURITY
The Vital Systems Security collaboration examines how, today, security is being constituted as an object of knowledge, intervention, and political reflection. It proposes that the security of vital systems such as energy, transportation, communication and health is one norm in relationship to which security is being reproblematized. A central goal of the collaboration is to examine these issues through collective, conceptually driven inquiry that addresses rapidly developing contemporary problems.
