As Congress Weighs Homegrown Terrorism, Study Shows Phenomenon Is Rare

There's a fight brewing in Congress over upcoming hearings on homegrown Islamic terrorism.  The New York Times reports that Republican Peter King of New York, the chairman of the House Homeland Security committee, plans to call mostly Muslim and Arab witnesses to make a point that there's little cooperation from Muslim Americans on reporting terrorism suspects.

But a new study finds that Muslim Americans are the single biggest source of information on potential terrorists.   The study also points out that 11 Muslim Americans have carried out terrorist attacks since 9/11, killing 33 people, including the 13 killed by the Fort Hood shooter.  We speak with study author Charles Kurzman, who teaches sociology at the University of North Carolina Chapel Hill.
