Tim Evans has kindly drawn my attention to this which I missed earlier:-
If one neighbourhood can do it, why not everywhere? We could soon make “The [State] Police” as redundant as the State Phone company, the State “Post Office”, and the State “hospitals”.
…history teaches us that it is very dangerous to allow “modern” “big” States, such as Russia, Prussia and the UK, to get involved in the minutiae and provision of policing services. Any sort of lefty mountebank could subvert their objectives.
