Compost,

I like the list. Missing are prison staff trainers, if not adequate prisons - construction staff maybe available, designers and the like maybe not. And cartographers, little can be done without maps even in this so called digital age.

I have assumed pre-trial detention and imprisonment are the route being taken, not "catch, kill or release".

A key factor is understanding how country actually 'X' works and the extent of non-national / local access such as the IMF, banks, airlines, media and NGOs. Will they talk to you? Is there an overseas community? Sometimes the answers are closer than you think.
