This is an interesting article about the Sudan and their tyrannical policies. It's a bit long but a great read:

Imagine living in a place where if someone wants your property, instead of renting or buying it, they decide it is cheaper to kill you, and then proceed to make a law that entitles them to do this unabated, and guess what, you can't turn to the government for justice because these guys are the police and the army!!! So all you can do is run for your life. With your children and family, you run.

In the Sudan, the government has a written policy to clear the land within a 50 Kilometer radius of any oil rigs of all human life. So if you happened to live on a piece of land and oil was discovered there, no one asks you how much you would be willing to take for it. No, you don't sign a lease agreement with anyone giving them permission to set up shop on your property for a certain length of time. The government militias come in tankers and bomber planes and get rid of you, so you teach your kids how to recognize the sound of a bomber from the sound of a relief food airplane, so that they run for cover when they hear the former, and run for food when they hear the latter -- either way, running for their lives.
