Norwegian mass killer Anders Behring Breivik (R) adjusts his handcuffs as he arrives to hear the verdict in his trial at a courtroom in Oslo August 24, 2012. Breivik was jailed for a maximum term on Friday when judges declared him sane enough to answer for the murder of 77 people last year, drawing a smirk of triumph from the self-styled warrior against Islam. An unrepentant Breivik, 33, gave the Oslo court a stiff-armed, clench-fisted salute before being handed the steepest possible penalty, 21 years. His release, however, can be put off indefinitely should he still pose a threat to a liberal society left traumatised by his bomb and shooting rampage last July.
