BP isn't alone in the stocks here — cement contractor Halliburton (THOSE guys!) and Transocean, which owned the rig, also made mistakes.

It's kind of amazing/appalling that this even needs to be said at this point, but you know the government: they like to make sure things are done right. Or anyway they like to make sure things are done slow.
