Dunno, depends if they're in a particularly sadistic mood that day. If not, and they're feeling a bit generous, then yes, I would say they would try and get guns around, so people can actually try and defend themselves. Only to the major cities at first, London, Birmingham, Manchester, Leeds, Newcastle, Bristol, Liverpool, then around to the more populated cities. We'd need petrol to get about. I never even suggested petrol would evaporate, someone else may have suggested that. You were just cutting off most survival methods, so I thought you might rule out the use of petrol as well. It's like a bizarre episode of MacGyver.
