When did we become a nation of police informers?

There’s a danger that in what follows your columnist may seem to be recommending an attitude. Please don’t think that. It’s true that I would never shop a friend for drink-driving — but frankly I doubt I’d shop a friend for murder. This column isn’t about what we should do if we know a friend drink-drives — responses will be various and variously arguable — but about shock at my own serious misreading of my countrymen.

I was tooling along in our Mini on the first Saturday of the year, with BBC Radio 2 playing. It was Graham Norton’s fizzy and engaging morning show, where a regular feature is his ‘Grill Graham’ slot in which listeners contact him with personal, social or moral dilemmas. Mr Norton may suggest his own answers, while quoting advice from other listeners too.

‘Karen’ had asked what she should do about her friends, a couple who come to dine (with others) and who then drive home after drinking too much.
