For a moment I thought you meant spooky a la CIA! That agency seems to keep a large number of staff there, not surprising for a country as important as the world's no.1 oil producer.

One J. Michael Springmann claimed that "most" of the staff at the US consulate in Jeddah belonged to intelligence agencies, when he worked there in the 1980s; elsewhere he calls them "CIA". He also said that 15 of the 19 "9/11 hijackers" got US entry visas at this consulate. Springmann speculated that the massive terrorist attack that resulted made an ideal excuse for increasing control of the Mideast oil lands, and in the borderlands of the former Soviet Union.

If you like a good conspiracy theory.
