Such a mission can be fraught with danger. In the summer of 2006, Kashi, along with his local "fixer" (guide/assistant), was arrested at gunpoint by a Nigerian naval task force, apparently for photographing an oil facility from the river without permission. The two men were held and interrogated for three harrowing days before the authorities released them. "People in the local human rights movement had been working for our release," Kashi says. "Had it not been for their efforts, and those of others, I'm convinced the situation would have lasted a lot longer and been a lot uglier." At one point, Kashi thought he might face death. "The most frightening thing about the experience is once they have you they can do what they want with you," he says. "This is the part that constantly haunted me while I was being held - the not knowing. They did let me go, but I was detained because the government sees me as a threat there."
