I give up on describing the panels. I've written and deleted more than once. I am not entirely satisfied by my own contributions, but the panels themselves went very well, and I enjoyed doing them. One of my fellow panellists wants to keep in touch, which is lovely. All I can say about the panel discussing torture is, in the words of Basil Fawlty 'Don't mention the war. I did once but I think I got away with it.' ie - I blew my top, in a quite unnecessary fashion, but I think most people gave me the benefit of the doubt.
You will be pleased to know that the conclusion of each panel was that science fiction fans are the last, best, hope of humanity. It's so obvious when you point it out :-)
