From my understanding, the paperwork clearly traces the ludicrous decision to use seawater to counter the ocean pressure back to BP. The other owners have an obligation to be in on the decision and to turn BP in to the appropriate regulatory agency. Haliburton should be well aware of the danger presented by the decision and should have refused to dig. It appeared cheaper for those companies to just go along for the ride if things worked out and there wasn't a disaster. The federal government should investigate what is being done beforehand, but I don't think that is feasible, unless you think utopia is achievable. The government should have stepped in sooner, but hasn't been able to get out of its own way for decades, if not more.
Its time to bite the bullet and invest in an infrastructure that doesn't involve oil. I don't think this country has the patience or education for something like that- we are a bunch of babies that want what we want- and we want it now.
