Having been told by a Joss that Reggies now get equivalent training to civvy plod, I propose that we send them all up to London to help maintain the peace. There you go ladies, hats and bats - show us what you can do.
Yes, that is true (Home Office-approved training; powers under PACE/CPIA/RIPA, etc., and holders of Warrant Cards.)
However Service Police (RN/RAF and Army) do not have all the powers of a Home Office police officer because they have not been sworn in as a Constable by a Magistrate and therefore have some limitations on power of arrest over civilians. Martial Law has not been declared - to my knowledge! - so there is no requirement for the military (police or otherwise) to be deployed on the streets.
I doubt there is much use for printing daily orders and drinking tea in London at the moment. Although I suppose they would have a field day picking people up for not ironing there trackies and polishing their Reeboks.
