This is the fourth annual report on Muslim‐American terrorism suspects and perpetrators published by the Triangle Center on Terrorism and Homeland Security. The first report, co‐authored by David Schanzer, Charles Kurzman, and Ebrahim Moosa in early 2010, also examined efforts by Muslim‐Americans to prevent radicalization. The second report, authored by Charles Kurzman and issued in early 2011, examined the source of the initial tips that brought these cases to the attention of law‐enforcement authorities. The third report, issued in early 2012, focused on cases of support for terrorism, in addition to violent plots. This fourth report adds educational and occupational information, as well as a comparison with Islamic terrorism in Western Europe. To read the full report, please click here .
