Scientists from the National Oceanic and Atmospheric Administration believe they have a "smoking gun" after finding dead coral 4,500 feet below the surface in the Gulf of Mexico, seven miles from the Deepwater Horizon rig site. What a coincidence.

Using a submersible robot, scientists found "a brownish substance" on much of the dead coral, and Dr. Charles Fisher told the Times, "We have never seen anything like this at any of the deep coral sites that we've been to. And we've been to quite a lot of them." BP can just add this to its growing tab and all will be forgotten.
