From Scope and Method: "The 57 counterterrorism [CT] professionals interviewed for this article came from many different CT fields, in both the public and private sectors. The interviews were conducted using a structured format, and, with one exception, the author interviewed everyone in person. Participants were asked to reflect on their CT professions and their effects on them and to characterize their vocations' unique contributions to the overall CT enterprise. They were also asked to talk about their emotional, psychological, and interpersonal responses to their activities and to attempt to identify enduring effects of their work on themselves as well as on those closest to them, including colleagues, friends, and family. Finally, they described any deeper meanings-- political, scientific, philosophical, spiritual--that this type of work evoked in them."
