I sympathize with the medical team that decided to pull out. I can't imagine a more difficult decision, but it was probably the correct one.

Haiti has a long history of kidnapping, where foreigners are taken by violence and held for ransom by gangs/thugs. I don't think the 'quake would change the facts on the ground.

One opportunistic act by a few criminals could substantially delay or derail the arrival of help for a great many innocents.
