I glanced at a newstand today and picked up the headline on The Daily Mail and the first line of the story - apparently, a quarter of UK inhabitants claim never to have seen a police officer "on the beat" (patrolling the streets)
The headline is, of course, sickly sentimental: "Bobbies" are in the same world as Janet and John in sandals and satchels. "Our Bobbies" compounds the sentimentality with it implication that police officers are cuddly Dixons of Dock Green. There isn't a journalist on The Daily Mail who actually believes that. The sub who composed the headline probably had two fingers down his (surely not her?) throat as he wrote it.
As for this quarter of the population who have never seen a patrolling policeman, one must always remember that, at any one time, a quarter of the population is drunk, hungover, stoned, depressed, preoccupied, short sighted, blind, deaf, stupid and highly unlikely to spot an invasion from Mars if it landed on the pavement in front of them.
