Nearly a decade after the attacks of 9/11, the possible radicalization of Muslims living in the united States remains an ongoing concern. Just as the media coverage of the killing of Osama Bin Laden in early May was subsiding, several cases of Muslim-American terrorism suspects were in the press. New York police arrested two men accused of plotting to attack a synagogue. In Chicago, the trial opened of a businessman accused of being an accomplice in the deadly 2008 terrorist attacks in Mumbai, India. In South Florida, an imam and two of his sons, one of whom was also an imam, were arrested and charged with providing some $50,000 to the Pakistani Taliban.
Cases like these draw a lot of attention and raise the question of whether Muslim-Americans are increasingly turning to terrorism. To address this question, The Triangle Center on Terrorism and Homeland Security released a report in February—“Muslim-American Terrorism Since 9/11: An Accounting”—that aimed to document every Muslim-American terrorism suspect or perpe- trator in the period after 9/11 to the end of 2010 (the study did not include terrorist financing or non-violent cases). The annual totals by year are shown in the chart to the right.
