I guess my first point would be that I said, "fiduciary responsibility" not legal obligation.

I really loved this quote at the end... "the idea that good decisions are the product of orderly processes – is more alive than ever in public affairs. ...There is not, and never will be, such a science. Our objectives are typically imprecise, multifaceted and change as we progress towards them – and properly so. Our decisions depend on the responses of others, and on what we anticipate these responses will be. The world is complex and imperfectly known, and this will remain true however much we analyse it."
