There's a reason why the Obama Administration is now using the title "British Petroleum" and not the usual "BP".
BP is the primary on the leasehold of that drill site, therefore it's legally culpable. BP did apply pressure to Transoceanic and insisted not to stop drilling even though the warning signs were all there.
But this leak is part of a much greater issue called, '
Peak Oil'. We are taking more and more risks to get the Oil out of the ground.
I have bought and waiting to receive the movie/doc 'Collapse' which covers what will happen when Peak Oil is reached.
