Norwegian mass murderer Anders Breivik says prison isolation has radicalised him

Right-wing extremist Anders Behring Breivik, who killed 77 people in 2011, said on Thursday his more than five-year prison isolation has radicalised him, a key point in his lawsuit against the Norwegian state over his prison conditions.
I was radical to start but these past five years I’ve become much more radical
In July 2011 Breivik, disguised as a police officer, tracked and gunned down 69 people, most of them teenagers, at a Labour Party youth camp on the island of Utoya, shortly after he killed eight people in a bombing outside a government building in Oslo. He said he killed his victims because they valued multiculturalism. He was sentenced in 2012 to 21 years in prison, which can be extended indefinitely as long as he is considered a threat.

In prison, the extremist has three cells where he can play video games and watch television on two sets. He also has a computer without internet access, gym machines, books and newspapers.
Despite the comfortable material conditions, an Oslo district court last April found the Norwegian state guilty of “inhumane” and “degrading” treatment, in violation of the European Convention on Human Rights.
