"Nothing, Nothing, Nothing"

Nada. Zippy. Rien. Bupkus. That's what French police say they have on a supposed terrorist on the loose. Police do know a passenger failed to show up for a flight out of Paris, thus triggering the recent spate of air traffic lockdowns. Further, it seems this person has the last name "Hai," which is the same name of an Afghan citizen on some U.S. terror-watch list.

To recap, that is a three letter match at the heart of this massive to-do.
