from abc: The right wing extremist who has confessed to murdering 77 people -- many of them teenagers -- in a shooting and bombing spree in Norway cried at the start of his trial today, but not for his victims. Anders Breivik told the court he acknowledged the mass murder but pleaded not guilty, claiming it was done in self-defense as part of his war against "multiculturalism" in the European nation. He expressed no emotion as he entered his plea but broke down and had to wipe away tears when the court played a portion of a propaganda video he had made in support of his new "crusade" in Norway. Breivik is accused of carrying out the July 2011 bombing in Oslo, Norway, that killed eight people, followed by a shooting spree at a nearby youth summer camp that claimed another 69 lives... In his manifesto, Breivik said that getting arrested and put on trial was just another part of the overall plan. "Your arrest will mark the initiation of the propaganda phase," he wrote. "Your trial offers you a stage to the world."
