The landmark study just published, “Sharia and Violence in American Mosques” (Kedar M, Yerushalmi D. The Middle East Quarterly, Summer 2011, Vol. 18, No. 3, pp. 59-72) sought to expand considerably upon the NYPD’s post-hoc, case study approach—systematically gathering objective survey data, with much greater methodological rigor—and address these two a priori questions: I) Is there a robust association between observable measures of religious devotion, coupled to Sharia-adherence in US mosques, and the presence of violence-sanctioning materials at these mosques?; and II) Is there a robust association between the presence of violence-sanctioning materials at a mosque, and the advocacy of jihadism by the mosque’s leadership via recommending the study of these materials, or other manifest behaviors?
