Ironically his manifesto is apparently what led to FBI arresting him. > The big break in the case came in 1995. The Unabomber sent us a 35,000 word essay claiming to explain his motives and views of the ills of modern society. After much debate about the wisdom of “giving in to terrorists,” FBI Director Louis Freeh and Attorney General Janet Reno approved the task force’s recommendation to publish the essay in hopes that a reader could identify the author. > After the manifesto appeared in The Washington Post, thousands of people suggested possible suspects. One stood out: David Kaczynski described his troubled brother Ted, who had grown up in Chicago, taught at the University of California at Berkeley (where two of the bombs had been placed), then lived for a time in Salt Lake City before settling permanently into the primitive 10’ x 14’ cabin that the brothers had constructed near Lincoln, Montana. > Most importantly, David provided letters and documents written by his brother. Our linguistic analysis determined that the author of those papers and the manifesto were almost certainly the same. When combined with facts gleaned from the bombings and Kaczynski’s life, that analysis provided the basis for a search warrant. https://www.fbi.gov/history/famous-cases/unabomber https://www.fbi.gov/history/famous-cases/unabomber
