I watched the congressional hearing wherein the principals of BP, Halliburton and Transocean blithely blamed one another for everything. BP, however was stellar. they admitted that their claim of their ability to deal with a disaster was a damned lie, that they failed to observe even basic industry standards of safety, they lied about the size of the problem, etc. I was also absolutely impressed with the courtesy the congressional inquisitors showed this merry band of (as far as I could tell); liars, greedy jerks, incompetents, and damned fools.
Perhaps this courtesy has something to do with appreciation one shows toward them that brought you to the party?
