Breivik had set up his own business, Breivik Geofarm, and a month ago had started to run an organic farm in Hedmark in eastern Norway. There he reportedly produced and stored fertilizers that he was able to use in explosives.
He was known to be active on the internet, expressing extremist Islamophobic views on forums and criticizing immigration policies.
He recently claimed that politics today was not about socialism vs. capitalism but nationalism vs. internationalism. He argued on a Swedish news website that the media were not critical enough about Islam and claimed that Geert Wilders' Party for Freedom in the Netherlands was the only "true" party of conservatives.
He argued that socialism was breaking down traditions, culture, national identity and other societal structures and that this in turn made society weak and confused.
On July 17 he set up a Facebook and Twitter account, posting a single tweet, "One person with a belief is equal to the force of 100,000 who have only interests."
He claimed to be well-read and worshiped the Norwegian World War II hero Max Manus. On his Facebook profile he listed his favorite books as "The Trial" by Franz Kafka and "Nineteen Eighty-Four" by George Orwell and his favorite television show as "Dexter," a series about a Miami police forensics expert who moonlights as a serial killer of criminals whom he believes have escaped justice.
