That's fair enough.
Professor Mason, you talked about the application of the assessment. First, is the legislation adequate, or do we need to change that, or change the method of assessment?
Secondly, Professor Byers talked about how dangerous drones are . Is there any special consideration that should be given in dealing with arms exports of drones, or the kind of drone technology we're talking about here that's the essence of a drone? Could you reflect on that briefly, please?
