 Throughout the manuscript, produced on a typewriter without the capacity for italics, Kaczynski capitalizes entire words in order to show emphasis. He always refers to himself as either "we" or "FC" (Freedom Club), though there is no evidence that he worked with others. Donald Foster, who analyzed the writing at the request of Kaczynski's defense, notes that the manuscript contains instances of irregular spelling and hyphenation, as well as other consistent linguistic idiosyncrasies (which led him to conclude that it was indeed Kaczynski who wrote it).
