The development of the situational prevention framework to combat terrorism has broadened the traditional focus of these strategies on the immediate situation. This chapter discusses the diverse temporal and spatial focus of the set of situational techniques Clarke and Newman (2006) have proposed as a response to terrorism. As a consequence of this increased diversity, the situational prevention strategies for terrorism bifurcate to parallel the epidemiological high-risk and population approaches to disease prevention. Further, these population techniques incorporated into the expanded situational prevention framework are entirely consistent with those of theories discussed by psychologists, anthropologists, sociologists, and lawyers.
