I don't think anyone thinks they shouldn't be held accountable. The issue seems to be whether punishment should be meted out before or after a fair and impartial trial...
Statements like this are why we have laws against vigilante justice.
To those that think this is vigilante justice, remember that BP actually agreed to the $20 billion escrow account to pay for the damages. They could have fought that in the courts for sure....just like Exxon has done for years. Sure, pressure was put on them, but they were in no way forced to do it. Perhaps you'd like to characterize it as a "shakedown" as Joe Barton did yesterday...something even most of the people in in own party has condemned.
