Two reactions to the Home Secretary's recent proposal to restore, experimentally, the punishment known as ' short, sharp shock '. Its aims are simple: for a short time life is made so tough that young offenders will be both punished and then, deterred for life. But will it work?

So what's the answer? On film and in the studio. David Calder , Michael Dean , Jack Pizzey and Nick Ross put that question, to both sides.
