let me ask you this: are there any circumstances in which the oil spill would be, roughly, nobody's fault? or is that by definition impossible? what if, you know, they hit a sudden, you know, methane pocket or something that they could not have known was there? or something? or if there was just a bizarre concatenation of extremely unlikely events? what i would say is: you've got to look and see whether anyone was at fault, and if so why and to what extent. but the "it's a fucked-up world" move has to be one of the possibilities. i think rand paul is right, that is, that the whole idea is that we have to hang somebody. we still live for the anthropomorphic explanation: that it has to come back to somebody's greed and evil, who can then be punished; this is just to say that we can't face an amoral material universe. katrina was a beautiful example: it was going to have to turn out to be someone's fault: brownies's, the corps of engineers, the forces of global warming.
now one reason it has to turn out to be someone's fault is that someone has to pay; i mean literally someone's got to pony up the billions. but the impulse is more powerful than that. and working backwards from the disaster, it's going to be extremely easy to see some things that should have been done differently, even if at every moment of not doing things differently, the people involved made sound decisions relative to the information at their disposal, or made the decisions you would have made in their place, etc.
notice i am not saying that no one is at fault. i'm saying that as you do the investigations, that's more or less one of the possibilities. face up. and realize that burning people at the stake will not really expiate their sins or our sins or make the world make moral sense.
