Unfortunately, the best solution would have been using the proper mud, instead of going cheap and using seawater in the first place. BP shouldn't get to call the solution to this. As many solutions as possible should be implemented immediately. The economy and ecology of a big part of our country is at stake.
Personally, I don't care what punitive actions are taken- now or afterwards. The leak must be sealed at any cost. I don't care if BP remains solvent or goes under- doesn't affect me either way. Personally, I think they will go under. Also- I laugh at the people who feel bad for the shareholders who did nothing wrong.........people invest in tons of companies that screw up and fail, I don't shed tears for them either. If BP falls, another shall rise.
