I understand what the noble Lord is saying, and I shall develop my argument further.
I have referred to away-weekend table-top exercises that I attended as part of keeping my “certificate to practise”, if you will, my continuing professional development as an advanced trained public order senior officer. We were told the maximum number of police officers, horses and so forth that were available to us and we were often presented with scenarios where the level of disorder anticipated led one to contemplate banning the protest entirely or imposing severe conditions. We were divided into syndicates which separately presented their proposals for dealing with the scenario. Invariably, syndicates that advocated an outright ban or severe conditions found that they ran out of resources to implement the plan. I do not know whether the noble Lord, Lord Hogan-Howe, has benefited from this sort of advanced public order training, but that is my experience. He has his experience, and I have mine.
