DENVER, Colo. (KKCO) - The passages copied by Anders Behring Breivik appear in the first few pages of Kaczynki's manifesto. Breivik changed a Kaczynski creed on leftism and what he considered to be leftists' "feelings of inferiority" - mainly by subsitituting the words "multiculturalism" or "cultural marxism" for "leftism."

Breivik is accused of killing at least 93 people Friday by setting off an explosion in downtown Oslo and then gunning down campers on a nearby island. Kaczynski is in federal prison for mail bombs that killed three people.

Breivik did not cite Kaczynski, though he did for others whose writings he used.
