The judges in the case of Anders Breivik, the young Norwegian who murdered 77 of his compatriots supposedly in protest against his country’s social and political policies (thus creating more victims per head of population in Norway than did the September 11th bombers in America), found him to have been fully responsible for his actions, and sentenced him to imprisonment as an ‘ordinary’ criminal. They did not yield to what must have been a strong temptation to accept the following specious bar-room syllogism:
No one but a madman would have killed 77 people.
Breivik killed 77 people.
Therefore Breivik was mad.
