After the Christmas airliner attack, the recent spate of domestic terrorism arrests, and the Fort Hood shootings, people are understandably concerned about the possibility of homegrown terrorism involving Muslim Americans. But while the potential for this form of terrorism is real, it is largely overstated.

Despite a troubling spike in terrorism arrests and incidents in 2009, terrorist activity by Muslim Americans has been rare. In the 100 months since 9/11, 139 Muslim Americans have been accused of planning or carrying out terror-related violence. To put this in perspective, more than 136,000 people have been murdered in the United States since 9/11, and only 31 of those murders were committed by these Muslim Americans.

Together with University of North Carolina sociology professor Charles Kurzman and Duke religion professor Ebrahim Moosa, I have been studying Muslim Americans for the past two years to learn about how they deal with the threat of radicalization within their communities and to identify ways to help prevent homegrown terrorism in the future. We found that:

Muslim American organizations and the vast majority of individuals we interviewed firmly reject extremist ideology that justifies the use of violence to achieve political ends.

Muslim Americans have taken a number of positive steps to reduce the potential for radicalization in their communities. They have consistently spoken out against terrorist incidents. And they have counseled, and sometimes cast out from mosques and community groups, those expressing radical views.
