Well, I'm going to say the same as other witnesses. I think increasingly we are, and those Omand questions are an example of the sort of questions that you might want to note and just keep an informal note of so that -- if people challenge you.
But in some respect it's not so very different from the so-called Reynolds rules which our investigative journalists and other reporters have been using for a long time. Because it's helpful. It's helpful to be able to keep a log of what you have asked people, when you put it to them, what their answers were because it may give you some protection in law.
