Breivik trial: Guard thought killer was policeman A youth camp guard who survived Anders Breivik's shooting spree on Uteoya island has said that he was convinced the mass killer was a policeman. The court trying Breivik has been shown images of the uniform and ID he used to lure those on the Norwegian island into a false sense of security. He went on to gun down 69 people, many of them teenagers. Camp guard Simen Braenden Mortensen, who was interviewed after giving evidence in court, said he thought that the "police officer" had suffered a mental breakdown when the shooting started. When asked whether he still thought the man was a policeman, Mortensen replied: "Yes, I had that perception for a long time." Breivik admits the killings at the Labour Party summer camp as well as a deadly car bomb attack in Oslo. But he denies criminal responsibility, describing his actions as a counter-attack against multiculturalism. More about: Justice, Norway massacre, Shootings, Survivors, Trial
