Anders Behring Brevik was the sole man who killed all those people in Norway. He was economically libetarian, ultra-social conservative, and hated "Marxists", and Muslims. He killed mostly members of Norway's ruling Labour Party which promotes immigration, and social democracy. He was actually a prominent member of Norway's racist Progress Party for quite some time. He apparently saved up to have a escort before the shooting, because apparently that was the Christian thing to do.
