WASHINGTON — A new study of homegrown terrorism involving Muslim Americans suggests that the alarm bells set off by Republicans in Congress over sleeper cells of Islamic extremists may be much too loud.
Despite warnings of a potential wave of violent attacks hatched on U.S. soil, research by the Triangle Center on Terrorism and Homeland Security finds that the number of attacks committed by Muslim Americans has fallen for the second year in a row. According to the study, 20 Muslim Americans carried out or were arrested for violent terrorist crimes in 2011, down from 26 in 2010 and 49 in 2009.
Since the Sept. 11, 2001, attacks, the report said, 193 Muslim Americans have been arrested or convicted of violent terrorist acts. Last year was an average year for such offenses, the Durham, N.C.-based center said.
