Rogue economist almost got sent to Guantanamo :: Freakonomics

QUOTE\ It didn't occur to me that my latest research was going to get me into trouble. I've been thinking a lot about terrorism lately. Among the things I had in my carry-on was a detailed description of the 9/11 terrorists activities, replete with pictures of each of the terrorists and information about their background. As well as pages of my scribblings on terrorist incentives, potential targets, etc. It also was the first thing the screener pulled out of my bag. The previously cheery mood turned dark. Four TSA employees suddenly surrounded me. They didn't seem very impressed with my explanation. When the boss arrived, one of the screener says, "He claims to be an economics professor who studies terrorism." /UNQUOTE
