Churchill wrote an essay in September 2001 entitled '' On the Justice of Roosting Chickens '' . In it , he argued that the September 11 attacks were provoked by U.S. foreign policy . He compared the role of financial workers at the World Trade Center in " ongoing genocidal American imperialism " to the role played by Adolf Eichmann in organizing the Holocaust . In 2005 , this essay was widely publicized when Hamilton College invited Churchill to speak . This led to both condemnations of Churchill and counter-accusations of McCarthyism by Churchill and supporters . Following the controversy , the University of Colorado interim Chancellor Phil DiStefano said , " While Professor Churchill has the constitutional right to express his political views , his essay on 9/11 has outraged and appalled us and the general public . " A documentary called '' Shouting Fire : Stories from the Edge of Free Speech '' , broadcast on HBO , prominently features Churchill 's case in addressing the issues of free speech and First Amendment rights
