I've never seen any problems there, but it does make you pay attention to all the stories. There have been times when the company will restrict travel to that area to only "necessary" trips, but that makes me really wonder why someone would go there if it wasn't necessary.
When I was with Motorola, they had a policy that when you flew into Bogota, Colombia you had to take the trip from the airport to your hotel in an armored limo. It was sort of nice to have that experience, but it REALLY made you nervous about why the company would spend that kind of money on a cab ride!
