In the days before the September 11th attack, FBI authorities in Minneapolis tried --and failed-- to get a warrant to search the computer of suspected terrorist Zacarias Moussaoui (Moo-SOW-ee). Moussaoui was taken into custody in Minnesota after raising suspicions at a Twin Cities flight school. After his arrest, officials asked FBI headquarters in Washington for permission to search Moussaoui's hard drive, but were told they didn't have enough evidence to justify a surveillance. Daniel Klaidman (KLIDE-man) is Washington Bureau Chief for Newsweek and one of the reporters who broke the story in the most recent issue of the magazine. He says the Foreign Intelligence Surveillance Act, or FISA (FIZE-uh), provides specific critieria for getting a warrant on a foreign national.
