It suggests a bygone age when "If you want to know the time, ask a policeman" was advice given to children , every area of every town had a constable walking a 'beat' of a set route of a few streets and every village had its very own policeman, "the village bobby". When you see the word in a newspaper it is either being used humorously or to recall such a figure of the past. What we call them now depends who we are.Londoners, particularly older ones still call them "Old Bill" (always in the singular) or "the old Bill" [ A reference to an old,cynical, grizzled, world-weary but all-knowng soldier, Old Bill,who featured in a First World War comic strip ] 'Bobby' comes from Sir Roert 'Bobby' Peel who founded the Metropolitan Police;
