Law enforcement officials were quoted as saying that the recent failed attacks in London have provided important new clues about possible tactics. The London attackers use of the Internet left important clues that are being used to decode other e-mails that had initially been deemed unimportant but are now taking on new significance.
The ABC report yesterday came on the same day the Chicago Tribune quoted Homeland Security Secretary Michael Chertoff as saying that the nations faces a heightened chance of attack this summer.
"I believe we are entering a period this summer of increased risk," Chertoff told the Chicago Tribune's editorial board in an unusually blunt and frank assessment of America's terror threat level.
