What *could* he have been thinking?

Dana Kennedy does her dangedest to suss out a possible motive for the murder of two American servicemen:

Who is Arif Uka and why is he suspected of opening fire today on American servicemen on a U.S. military bus at Frankfurt's airport?

The attack killed two airmen and wounded two.

Investigators were scrambling to find out more about the 21-year-old Kosovo citizen after they say he fired shots at U.S. military personnel on a bus outside Terminal 2 at one of Europe's busiest airports this afternoon.

Rep. Patrick Meehan, a member of the U.S. Homeland Security Committee, said it looked like a terrorist attack. The New York Times quoted a man whose office is near the site of the shooting who seemed to back up that assertion.

Speaking on condition of anonymity to protect his business, the man said witnesses told him that the gunman first talked to the military personnel to find out who they were and then opened fire, shouting "God is great" in Arabic.

Well, Dana, we're here to help. Speaking on condition of anonymity, we speculate that the reason he's suspected is that several people saw him do it. As for the other business, well, doesn't every street thug these days shout "God is great!" in Arabic? Blue skies! -- Dan Ford
