The question: How to rid London's streets of the idiot demonstrators? Giving them a bloody good soaking would very quickly send them packing. Boris had the right idea. Why they were never used I cannot understand. Alternatively, in the case of Waterloo Bridge for example, fence them in. A fence at either end of the bridge and no one is allowed in or out. No food, no potty breaks, no water. They'd pretty quickly lose interest. With so many good ideas, I really should be running the country.
