Anticorruption police in Nigeria — must be a busy bunch — plan to file charges against and issue arrest warrants for Dick Cheney and other current and former Halliburton officials over their alleged involvement in bribing Nigerian officials for a liquefied-natural-gas contract. Halliburton and KBR, a former unit of Halliburton, pleaded guilty to similar charges in the U.S. last year and settled for $579 million in fines. [Reuters]
