This statistic really reinforces a point that I keep making. We are putting effort and treasure into fighting terrorism orders of magnitude out of proportion to its impact.
Out of more than 150,000 murders in the United States since 9/11 -- currently more than 14,000 each year -- Islamist terrorists accounted for fewer than three dozen deaths by the end of 2010. Part of the credit for this is surely due to the law-enforcement officers and community members who have worked to uncover plots before they could be carried out. But fewer than 200 Muslim Americans have been involved in violent plots since 9/11, most of them overseas, so credit for the low level of violence must be due primarily to the millions of Muslims who have refrained from answering the call to terrorism.
