What happens in Vegas stays in D.C.: Something's happening in Vegas.
Of course, media reports have pegged Vegas as a major site of interest to al'Qaeda. Given the terror group's evident continued interest in plane-based attacks, counterterror officials should be worried; a plane coming in for a landing at McCarran International is a matter of seconds from New York, New York or any of the other casinos on the strip. That proximity means that it would be almost impossible to distinguish a 9/11-style attack from a legitimate landing in time to stop the rogue plane.
