Want to understand why there's such resentment against Tony Blair, and why Chilcot today will only deepen the sense of outrage? The very smart Gordon Lynch has the best thesis I think I've read.

Roughly, you need a concept of the sacred - which in the secular context just means that which seems inviolable. The life of a child would be an obvious example. And so would certain aspects of the democratic process, not least when millions walk the streets in protest and democratic leaders respond by acting as monarchs. Or when a war is pursued with disregard for loss of life, so that deaths are not even counted, provoking not just shame in those whom the politicians are supposed to represent, but a sense of pollution, as if something fundamental has been spoiled.

The thesis is that when the sacred is breached, some kind of restitution is required - a ritual of apology or a removal from public life. Chilcot won't achieve that. It'll merely remind people of the breach that's occurred. And in turn, contribute to the sense that our political system is broken.
