The New York Times has a very good article on how the Deepwater Horizon catastrophe came to be. There’s lots of blame to go around. They paint BP as the main culprit, citing numerous instances in which BP failed to abide by its own best practices. Government regulators went along with everything, and also failed to respond in a timely fashion after the disaster. Halliburton complained that what BP was doing was unsafe, but apparently didn’t refuse.
