Moore incorporates the concept of bowling into the film in other ways as well. For example, the Michigan Militia use bowling pins for their target practice. When interviewing former classmates of the two boys, Moore notes that the students took a bowling class in place of physical education. He suggests that this might have very little educational value and the people he interviews generally agree, noting how Harris and Klebold led introverted lifestyles and had careless attitudes towards the game, and that nobody thought twice about it. Moore questions whether the school system is responding to the real needs of students or if they are reinforcing fear. Moore also interviews two young residents of Oscoda, Michigan. Moore suggests a culture of fear created by the government and the media leads Americans to arm themselves, to the advantage of gun-making companies. Moore suggests that bowling could have been just as responsible for the attacks on the school as Marilyn Manson, or even President Bill Clinton, who launched bombing attacks on Serbia at the time.
