WASHINGTON (AP) — The question has never stopped being asked since the morning of Sept. 11, 2001: What next?
Billions of dollars and the efforts of untold thousands of people around the clock are aimed squarely at finding the answer.
The next big terrorist attack could be cooked up in a lab, giving new meaning to technology at the cutting — or deadly — edge. It could come again from the sky, in a frighteningly similar way. Or in some completely new way. Even now officials are chasing a "specific, credible but unconfirmed" threat of a car-bomb attack in New York or Washington, timed to the 9/11 anniversary period.
