The Deepwater Oil Spill

I came across this NT times Graphic on the Oil Spill in the Louisiana Gulf recently. So far BP and associated entities have been unable to completely seal off the spill resulting in enormous damage both to the environment, livelihood as well as BP's reputation and share price.
A number of news reports and blogs talking of less than best practice in the well engineering & implementation as well as the inability of the company to fix the leak has lead to the grilling of BP's Chief Executive Tony Hayward being grilled by the US Congressional enquiry yesterday. According to the Australian ABC report "Mr Hayward has been accused of evading questions and ducking responsibility for what has become America's worst environmental disaster."
Yesterday we hear Mr Hayward has been moved aside and will no longer manage the oil spill. Private industry can move swiftly when it wants and needs to lift its public image.
Accountability of large corporations has always been problematic in our current democracy. With their large power base, earnings and multinational base, evading social responsibility has been the norm and our laws are made to allow the transfer of these too hard problems onto governments.
Thus the public again pick up the costs - monetary, environmental, social problems.
We will see if President Obama has the ability to call BP to account. It will also be interesting to see if the "no drill" rhetoric lasts much beyond the immediacy of the spill.
But when will the oil stop leaking???
