THE LONG READ: Does mass murderer Anders Breivik still pose a threat to the security of Europe?

Europe’s most notorious mass murderer, Anders Breivik, complained about his treatment in prison and has won his case against the Norwegian government. Relatives of his victims were not so lucky, writes Asne Seierstad

As Anders Behring Breivik entered the gym turned courtroom in Skien prison, the jail in southern Norway that has held him since August 2013, a smile crossed his lips.

He waited eagerly for one of the four guards who stood next to him to unlock his handcuffs. He looked around to see who was in the gym: Two dozen journalists and some prison officials. And then he looked in the direction of the journalists and raised his right arm in a Nazi salute.
