retro, surely only a fool would criticise the application of the law-keeping as set out in your post? I often watch the police programmes on Channel 5. The number of officers sent to scenes, the time officers spend getting prisoners booked-in, tested for drinking/drug-taking, the futile arguments by those under arrest to avoid prosecution etc., etc., etc. The times no charges follow a night in the cells. Makes me wonder why anyone would want to join the police to be abused and assaulted on a regular basis.
If only we could turn back the clock to the bobby-on-the-beat style of policing. I know that crimes have moved on a pace, when did you see Samurai swords, BB guns (at best) and huge quantities of drugs in the hands of villains in the 70's? Whatever crimes are committed thank heavens for the major part of our police force!
