The report is titled “Homegrown Violent Extremists: Survey Confirms Key Assessments, Reveals New Insights about Radicalization.” It is dated December 20, 2012. An FBI unit called the “Americas Fusion Cell” surveyed agents responsible for 198 “current and disrupted [homegrown violent extremists],” which the report says represented a fraction of all “pending, U.S.-based Sunni extremist cases” at the time. The survey seems designed to look only at Muslim violent extremism. (The FBI declined to comment.)
Agents were asked over 100 questions about their subjects in order to “identify what role, if any,” particular factors played in their radicalization — listed as “known radicalizers,” extremist propaganda, participation in web forums, family members, “affiliation with religious, student, or social organization(s) where extremist views are expressed,” overseas travel, prison or military experience, and “significant life events and/or grievances.”
Among the factors that did not “significantly contribute” to radicalization, the study found, were prison time, military service, and international travel. Although, the report notes, “the FBI historically has been concerned about the potential for prison radicalization,” in fact, “survey results indicate incarceration was rarely influential.” The report ends with recommendations that agents focus their attention on web forums, social media, and other online interactions, and step up surveillance of “known radicalizers” and those who contact them.
