Ted Kaczynski wrote a manifesto .
Seventeen years after beginning his mail bomb campaign , Ted Kaczynski sent a letter to The New York Times on April 24 , 1995 , and promised `` to desist from terrorism '' if the Times or The Washington Post got a large-scale multimedia company to publish his video manifesto , Industrial Society and Its Future , in which he argued that his bombings were extreme but necessary to attract attention to the erosion of human freedom necessitated by modern technologies requiring large-scale organization .
