So you need to drill an oil well offshore... What better place to drill than a dumping ground for unexploded munitions (things that go boom)!
Didn't know that the Gulf of Mexico was the largest dumping ground for munitions?
Neither did I! Apparently it's just 30 million pounds of explosives so nothing to worry about I guess...
S.N.A.F.U
For more info check out Crooks and Liars...
Just as an aside, Moldy Chum points out that since this disaster in the Gulf of Mexico began, the powers that be have granted oil and gas companies at least 27 exemptions from doing in-depth environmental studies of oil exploration and production in the Gulf of Mexico.
Makes all kinds of sense...
