From the Daily Telegraph:
The 32 year-old appears to have quoted verbatim large sections from the preaching of Theodore Kaczynski in his 1500 page online rant.
Breivik had “copied and pasted” almost a dozen key passages from the 69 year-old’s 35,000 manifesto, only changing particular words such as “leftist” with “cultural Marxist”.
It remains unclear what his motivations were, but experts said it appeared he had taken “inspiration” from Kaczynski whose two decade parcel-bomb terror campaign killed three people and 29 injured others.
Despite meticulous university thesis-style referencing through the manifesto, Norwegian bloggers discovered that passages quoting Kaczynski were not credited.
His “martyrdom operation” diary, titled “2083: A European Declaration of Independence”, discloses that he started preparing for the attacks for nearly two years.
