My Lords, my noble friend rightly mentioned the need for transparency, but does he accept that farmers who participate in the trials or, for example, in the Krebs trials on bovine TB, are doing a great service by providing proper scientific data under which case-by-case decisions can be taken? In those circumstances, do they not deserve some protection—if not by hiding the trial sites, at least by adequate police protection against illegal action by people who only want to trash, not to achieve scientific results?
