If I pour crude oil into the ocean, destroy the livelyhoods of fishing communities and kill a few of people on an oil platform in a gas fire (and destroy some evidence), I'll get a couple of hundred $k fine. If I buy a gun and go out and shoot the same number of people (and survive the manhunt) I'll get the rest of my life being a jailhouse bitch. Now, I wonder which I would choose?? Haliburton, do you have any vacancies???
Oh no, it's much better than that. If you pour crude oil into the ocean etc etc, you will wind up going to jail, because you are just one man. But if you operate a corporation such that such an outcome is inevitable, then you will get a fat bonus and the corporation will get a small fine.
