Oslo Killer's Lawyers Say He Is Sane OSLO - On the final day of testimony, defense lawyers sought on Friday to depict Anders Behring Breivik as being "of sound mind" when, by his own admission, he killed 77 people in Norway's worst peacetime atrocity, planting a bomb in central Oslo before gunning down 69 people, mainly teenagers, on the island of Utoya last year. A day earlier, prosecutors asked the court to order Mr. Breivik confined for compulsory psychiatric treatment instead of sentencing him to prison. Mr. Breivik has acknowledged the bloody acts on July 22, 2011, but has told the court he carried them out in self-defense to combat what he has termed the "Islamic colonization" of Europe. He has argued that an insanity judgment would detract from his cause. In a closing argument, Mr. Breivik's defense lawyer, Geir Lippestad, said Mr. Breivik accepts that the attacks were carried out in the way the attacks were described during the hearings. "That little, safe Norway would be hit by such a terror attack is almost impossible to understand," Mr. Lippestad said, according to The Associated Press. "July 22 was an inferno of violence," Lippestad said. But we must also look at how he carried out the attacks to see whether it was violence in itself or radical politics that was the cause. Mr. Breivik is expected to take the stand later on Friday. Prosecutors argued on Thursday that the almost 10 weeks of testimony in the trial of Mr. Breivik, 33, showed that he was psychotic at the time of the killings. "In our opinion, it is worse that a psychotic person is sentenced to preventive detention than a nonpsychotic person is sentenced to compulsory mental health care," Svein Holden, one of the prosecutors, told the court. The authors of the report said Mr. Breivik suffered a psychotic meltdown in 2006 when he lost money in a failed stock deal, moved back in with his mother in western Oslo and began playing World of Warcraft, an online role-playing game, for 16 hours a day.

Correction: June 22, 2012 A previous version of this article misstated the year in which Anders Behring Breivik, by his own admission, killed 77 people in Norway. It was in 2011, not 2010.
