BP has behaved very much like a nation unto themselves. In fact their behavior is much more benign if compared to actions by the United States military and decisions made by our Commander and Chief.
Reagan traded arms for hostages. Johnson supported spraying permanent mutagen poison on Viet Nam. Clinton spewed depleted Uranium oover Bosnia and both Bushs did so even more in Iraq.

Perhaps you don't like trans national corporations to behave like nations but you must have noticed their hiring of armies in numerous proxy wars in Africa and Asia.

As corporations they have no soul to damn and no body to kick but they do have a lifeblood of cash that can be made to bleed.
If you want to fight what a corporation does you can be killed as hundred in Bolivia were shot when Bectel privatized the water supply and made water unaffordable. It was a full fledged war and people died as a result. Corporations are as immortal as nations and will return to ravage each generation for profits that are often unbound by ethics, religion or law.

A less violent rebellion against evil corporate actions is the boycott. The lawsuit is another means that seldom works since time and money are on the side of corporations. Goverment regulations may establish law but then you need to police corporations to inforce the law which is most difficult.

The easiest thing to do is vote for candidates who are for consumer rights.

Foreign owned Fox news and business channels are on the side of corporations about 95% of the time and give a very emotional fear charged view of issues involving Enron heros and Wall Street genius'.

One thing that I have never seen in the Western World is a declaration of war against a corporation. Just look at the investment portfolio of any of the members of the foreign relations committee or the tri lateral commission. Look at the portfolio of the judge who overturned the US government request to cease only the deep water drilling that can't be reached by human hands.
Nope you can't commit war against a corporation yet they commit wars and unilateral decisions that kill, maim and bankrupt private individuals every day.

Free market you say? Look at the result of their free for all.
BP is a bit worse than most too big to fail corporations that routinely lie cheat steal and distort of a buck. They say Obama's government is out of touch. I say you need only take one look and listen to Tony Hayward to see who is out of touch.
