The experiment is being conducted, not by the Crown Office, but my right hon. Friend the Secretary of State for Scotland. It has been going on for some time. What is important is that its area of experimentation has been extended. What is most important is that it is now being carried on in Glasgow. Once we know fully what has been found out in Glasgow, I have no doubt that there will be a full statement both to the House and interested members of the public on the success of the experiment.
