As you probably know, an English teacher was recently arrested and imprisoned in the Sudan for allowing her schoolchildren to name a teddy bear Muhammad (it was the children's choice). Some Sudanese protesters called for her execution.
This sort of thing illustrates a simple fact that all travellers should bear in mind: some countries are relatively safe to live in and some are not. Considering the dismal history of the Sudan ever since independence, and how things are there now, why would any sane person decide to go and live there?
If you go and sit in a lion's cage, it may be horrific when you get eaten by the lion, but it shouldn't be surprising.
In this case the lady was allowed to escape without being eaten by the lion. She was lucky. Some reckless travellers have worse experiences.
