I mean that is a pretty strong statement. It's not like it was really possible to criminally charge Tony Hayward with being at fault for a faulty blow out preventer design, even though a number of people died. In some ways we were probably less safe with him fired, given that one of his objectives was to develop a much stronger engineering centric culture at BP.

In Brazil Vale and a number of its executives (along with the European dam inspector) are expected to be indicted. It will like be about falsifying documents related to dam safety.

Proving that the CEO is the one that should go to jail, while satisfying, is actually quite difficult. While I would probably agree with one piece of your sentiment, senior executives are often able to escape prosecution for things that are clearly illegal (looking at you HSBC), simply trying to lockup CEOs I don't think is the right way to go.
