BOB HERBERT — We were told by oil industry executives and their acolytes and enablers in government that deep-water drilling in the Gulf of Mexico would not cause the kind of catastrophe that we’ve been watching with an acute and painful sense of helplessness for the past three months. Advances in technology, they said, would ward off the worst-case scenarios. Fail-safe systems like the blowout preventer a mile below the surface at the Deepwater Horizon rig site would keep wildlife and the environment safe.
