Then comes this curveball:
One of the most widespread manifestations of the craziness of our world is leftism, so a discussion of the psychology of leftism can serve as an introduction to the discussion of the problems of modern society in general.
The manifesto interweaves two independent types of criticism:
Criticism of technology – part of this is sound, but the essence of it is probably disturbed;
Criticism of “leftism” – most of this is sound, and minor aspects of it are less convincing.
In 1994, Burson-Marsteller executive Thomas J. Mosser was killed by a mail bomb sent to his North Caldwell, New Jersey home. In another letter to The New York Times Kaczynski claimed that FC “blew up Thomas Mosser because […] Burston-Marsteller [sic] helped Exxon clean up its public image after the Exxon Valdez incident” and, more importantly, because “its business is the development of techniques for manipulating people’s attitudes.” This was followed by the 1995 murder of Gilbert Murray, president of the timber industry lobbying group California Forestry Association, by a mail bomb addressed to previous president William Dennison, who had retired.
One of Kaczynski’s tactics was leaving false clues in every bomb. He would make them hard to find deliberately to mislead investigators into thinking they had a clue. The first clue was a metal plate stamped with the initials “FC” hidden somewhere (usually in the pipe end cap) in every bomb. One false clue he left was a note in a bomb that did not detonate which reads “Wu—It works! I told you it would—RV”. A more obvious clue was the Eugene O’Neill $1 stamps used to send his boxes.One of his bombs was sent embedded in a copy of Sloan Wilson’s novel Ice Brothers.
The FBI theorized that Kaczynski had a theme of nature, trees and wood in his crimes. He often included bits of tree branch and bark in his bombs. Targets selected included Percy Wood, Professor Leroy Wood Bearson and Thomas Mosser. Crime writer Robert Graysmith noted, “in the Unabomber’s case a large factor was his obsession with wood.”
He bombed every two years according to the wiki list except for the six year period from 1987 to 1993. A bomb in 1990 would fit the pattern.
He used misdirection, planting misdirecting clues. He sent manifestos to newspapers and magazines. They were typewritten.
From FBI: taught at the University of California at Berkeley (where two of the bombs had been placed).
Worth pointing out: There is growing evidence that Theodore Kaczynski, otherwise known as the Unabomber, was a subject of the Project MKULTRA while he was at Harvard in the late 1950s.
