I think a lot of people are mad.
Just seems a little naive to trust BP blindly when it's already become apparent they lied about the amount of oil being released. I would assume they would do what any very large corporation would. Protect their own economic interests, first and foremost.
There's already a past history of collusion and impropriety between MMS and the industry. I don't trust any of them the government or BP in this, but at least there are some people in the government who give half a shit about the environment.
