TV journalist questioned after filming oil refinery

Greg Palast, a US-based journalist who often writes for The Observer and has worked for BBC's Newsnight, is under investigation by America's department of homeland security. He was questioned by officials after he and a fellow producer, Matt Pascarella, filmed the exterior of a huge Exxon oil refinery near New Orleans while working on a documentary about the hurricane Katrina evacuees. Many thousands of evacuees live in a trailer park encampment close to the refinery and Palast says: "We wanted to show that this human parking lot, with kids and elderly, is nearly adjacent to... a chemical-belching behemoth."
