Does a company that both builds oil rigs and cleans up oil spills have any motivation to prevent oil rig disasters?
That's the question some people in business and politics are asking themselves after Halliburton's purchase of an oil clean-up company 10 days before the Deepwater Horizon explosion that killed 11 workers and launched the worst oil spill in US history.
Some observers see a conspiracy in the actions of the company once headed by Dick Cheney. Halliburton, which built the cement casing for the Deepwater Horizon's drill, announced its purchase of Houston-based oilfield services company Boots and Coots for $240 million on April 9, just 11 days before the Deepwater Horizon explosion.
