A class of small children were being asked if they liked to watch programmes which had lots of violent action in them. One small boy’s eyes lit up as he told the reporter how exciting he found it, how it made him feel that he wanted to be strong like that, to run in and kick, and knock people down. ‘What do you want to be when you grow up?’ asked the reporter. The instant reply was: ‘A policeman’.
