The author of the study, Charles Kurzman, Professor of Sociology at the University of North Carolina Chapel Hill, said, “Of course, even a single terrorist plot is too many. But this trend offers a challenge for the American public: If we ratchet up our security concerns when the rate of terrorism rises, should we ratchet down our concerns when it falls?”
The study also reported that:
- The number of Muslim-Americans engaged in terrorist acts with domestic targets declined from 18 in 2009 to 10 in 2010.
- 75% of the Muslim Americans engaged in terrorist plots in 2010 were disrupted in an early stage of planning. This is consistent with the pattern of disruption since 9/11 (102 of 161 plots – 63% -- were disrupted at an early stage of planning).
- Less than one-third of the perpetrators did not come to the attention of law enforcement until after an attack was executed. However, a large majority of these Muslim American terrorist activities (35 out of 46 individuals) took place outside the United States.
- Domestic plots by Muslim-Americans are more likely to be disrupted than foreign plots. 48 of 69 individuals that plotted against domestic targets were arrested at an early stage of their activities.
- Eleven Muslim Americans have successfully executed terrorist attacks in the United States since 9/11, killing 33 people. This is about 3 deaths per year. There have been approximately 150,000 murders in the United States since 9/11. According to the FBI there were approximately 15,241 murders in the United States in 2009.
- Tips from the Muslim American community provided the source of information that led to a terrorist plot being thwarted in 48 of 120 cases involving Muslim Americans.
