> Supposedly even the "embassies are foreign soil" thing is more of an urban legend than legal reality.
It depends on what you mean by "foreign soil." Embassies are extraterritorial--as the name implies, it does not represent a claim on land, but the laws of the diplomat's country, not the host country, generally apply. This difference is sometimes crucial: being born in an embassy would not give you jus soli citizenship and GWB set up the terrorist prison in Guantanamo Bay to try to ensure that the Constitution wouldn't apply (since Guantanamo Bay isn't US soil, it's a base leased to the US by Cuba).
