In the mangrove swamps of Nigeria's oil-producing Rivers State, the Niger Delta People's Volunteer Force was in restless repose. A fighter worked out with dumbbells while others lounged on mattresses in front of a large outbuilding. One young man was reading, aloud in English, from a copy of Macbeth.

Their leader, Alhaji Mujahid Dokubo-Asari, was preparing to take me to a swamp facility where he claimed to refine oil taken from a pipeline operated by Royal Dutch/Shell, the energy multinational. (Asari says this is not stealing; it is the Nigerian government that is stealing.) He had just changed out of a black tracksuit into a bright orange jumpsuit with the Shell logo on the back. He put on a white hard hat belonging to Willbros, the oil services company. "Do I look fine?" he asked, running his hands over his ample stomach.
