It's the 10th anniversary of the terrorist attack by Norwegian far-right extremist Anders Breivik. On July 22, 2011 he detonated a car bomb outside the prime minister's office in Oslo. The explosion killed eight people. Brevik than drove to Utøya island where he shoot 69 people who gathered at a Labour Party youth camp. His victims were mostly kids. Breivik ended up behind bars, perhaps indefinitely. But what does he mean for the violent far right scene? How has this scene evolved? And can we expect another attack, similar to Breviks's? I talked to Professor Matthew Feldman, Director of the Centre for Analysis of the Radical Right. Listen to our conversation.
