A police officer checks room 250 of the central court in Oslo during a lunch break in Norwegian right-wing extremist Anders Behring Breivik's trial on April 20, 2012. Breivik, who is on trial for killing 77 people last July, insisted that he is sane. "I am not a psychiatric case," Breivik told the court when questioned by a lawyer for the plaintiffs about his understanding of "empathy", insisting "I am criminally sane."
