The Plame situation is an interesting one. I've not been able to work out where she was asigned when Libby blew her cover, but it might not necessarily have been getting shot. It is probable that a friendly European country would simply have declared her persona non grata and she would've been on the next flight out.
Not talking about her, or where she was WHEN someone blew her cover (I'm not betting that Libby was the leak either). I'm talking about every place she'd been for the last 10 to 20 years (or however long she was running around in that cover). Plame traveled a LOT, and not simply in Europe.
When her name came up, people ALL over the world started looking around to see who she might have talked to. In some of those places, putting a guy against a wall was considered a mercy. I'm sure some of them simply vanished and after a short and eventual interlude were dumped into a slit trench.
