According to Norwegian daily, Dagbaldet. Breivik explained about when and how he developed his radical attitudes during the last police interrrogation.
He told the police about the details of a shocking plan he developed in his 20.
He wanted to earn enough money to rent activity revenue, Oslo Spectrum. Here he would organize a large Muslim marking where he collected 50 000 Muslims. He would bury a bomb that would explode during the gathering. Later he thought that such a plan would be strategically bad because it would lead other people to have symphaty for the Muslims. In another interview, he said to police that he gave up the idea to attack against Muslims, because he did not consider them to be traitors as they are not Norwegians.
