I was surprised to see so much space given to the comments of Roger Brown and Geoffrey Alderman ("Watchdog makes case for a guard with teeth, but will it have the bite?", 28 May), who are beginning to appear like the Laurel and Hardy of a higher education comedy act. These are the harrumphs of two spectators, commenting on the match in which they were once serious players. We need sensible answers to complex questions that might assist the players still taking part in the game.
