Quote of the Day: Almost 10-Year Anniversary Edition

My quote of the day is the following: According to Mueller’s calculations, the United States would have had to stop four major bomb plots per day since the war on terror began for the security expenses that have been incurred to be considered cost-effective.

It comes from a very interesting article in The Boston Globe on research inspired by (or changed by) the 9/11 attacks. Free registration is required to read that article.

I found the article via a link on Aaron Clauset's blog entry on the probability of a 9/11-sized terrorist attack.
