Ayers objected to describing the WUO as terrorist in his 2001 book "Fugitive Days". "Terrorists terrorize," he argues, "they kill innocent civilians, while we organized and agitated. Terrorists destroy randomly, while our actions bore, we hoped, the precise stamp of a cut diamond. Terrorists intimidate, while we aimed only to educate." Dan Berger asserts in "Outlaws in America" that the group "purposefully and successfully avoided injuring anyone" as an argument that their actions were not terrorism. "Its war against property by definition means that the WUO was not a terrorist organization."
