Tony Blair was jeered at the Chilcot Inquiry when he said that he "profoundly" regretted the loss of innocent life in Iraq. This is a man who, more than any retired politician, is used to the sound of jeers – and worse: hysterical cries of "Bliar!", "war criminal!" and so on. So relentless is the chorus that the public has given up trying to listen to what he has to say, assuming that it is all glib self-justification (which, to be fair, is one of his specialities).
