In a litigious world few lawsuits surprise anymore; however, tonight Scott Pelley reports on a suit brought against oil giant Chevron, which owns Texaco. What makes this most stunning is that this lawsuit is brought by the natives of Ecuador in the Amazon rain forest, charging that oil drilling has polluted their environment. Also tonight, as Guantanamo Bay is closed, David Martin looks into what is happening to the detainees, including follow ups on those already freed for re-programming. Finally, Morley Safer re visits a family business that is perhaps the oldest in the world.
