For some it is the fashion today to insult British policemen with labels like 'pigs' and 'fuzz.' Other voices utter noises about law and order - sterner law, more order. Slogans don't help the police. But it is true that there is, today, a crisis of confidence between the British public and our police, traditionally the best in the world. Many of us suffer from wanting to have our cake and eat it, too. We want an orderly, safe society, but we resent the slightest loss of individual freedom as part of the price for this.
