Thank you.
Professor Lyon, in your earlier remarks you mentioned what I took to be a description of a deficiency in understanding all the issues around privacy and how to address them. I think you suggested that we wouldn't be ready yet for a complete overhaul of the act and that there was a substantial need for additional study into privacy matters. I think you even suggested a royal commission of some type, or some type of large-scale study.
Could you identify the things that we don't know? What do we need to research, and what areas require more study before a proper rewrite could be done, in your opinion?
