Interesting as this topic is, I think we should move on to the other areas of research, if I can. I'll turn to Professor Barnett first. I'm going to ask you a bit about the section in your witness statement dealing with culture, practices and ethics, being highly relevant to our terms of reference. You share with us in that section of your witness statement two personal experiences which I think are very helpful. If you wouldn't mind, can I ask you first about the experience about the celebrity on your street? Perhaps you can tell us a bit about it and then what you think you can pass on to the Inquiry as the kind of lesson to be learnt from that experience.
