Well,they better start installing them in existing wells and make them mandatory for all future wells.

The Deepwater Horizon oil rig that exploded last week was not outfitted with a safety device that might have prevented the massive oil spill now nearing the U.S. Gulf Coast. The device, known as an acoustic switch, is a last-resort protection against underwater spills, and is required by regulators in Norway and Brazil. Unfortunately, the U.S. has no such regulation for oil wells operating off of its shores.
