From Counterterrorism Blog: Weird incidents in US airports are raising questions

Counterterroism Blog notes a Saudi news report of some odd happenings at U.S. airports here:

...there have been a number of thefts of airport vehicles in US airports in the past few days including an United Air car on Chicago O'hare's airport.
also attempts were made in the Buffalo airport to stael (sic) authorized vehicles and supposedly airport authorities around the country have noticed strange people watching restricted areas in airports.

More probing?

My quick searches have revealed nothing along the lines of stolen airport vehicles...
