It would seem you're too ready to accept any crackpot allegation as necessarily true as long as it's anti-BP. How do you know the internal memos concerned verified calculations that were communicated to their spokesmen? Or that the accusations of faked safety tests aren't themselves completely bogus and malicious? You accept all that but show not the slightest interest in what Eddie Izzard has to say. Why? Because it's not anti-BP, that's why.
