From Wired.com. In 2005, the Naval Criminal Investigative Service put together a tip sheet for the FBI on how to run sources inside extremist organizations — even though it didn’t appear to have a lot of experience actually recruiting terrorist sources. An ideal source, it noted, was the same for counterterrorists as for terrorists: someone disciplined, capable of keeping secrets, and highly motivated.
Based on its interviews with Guantanamo detainees, NCIS found additional patterns within terrorist organizations: often, they’re people with low self-esteem who turn to religious extremism after experiencing a crisis. That makes them ripe for savvy agents to exploit.
