On July 22 Anders Behring Breivik, 32, set off a car bomb outside government offices in Oslo, killing eight people. Breivik then drove to the island of Utoya, where posing as a policeman he opened fire and gunned down 69 others, mostly teenagers attending a Labor Party youth camp. The killing spree was Norway's worst national tragedy since World War II. Breivik, who described himself as a Knight Templar, called the massacre "atrocious but necessary" to save Norway from an Islamic takeover. In November, psychiatrists labeled him a paranoid schizophrenic who was in a state of psychosis during the onslaught.
