David Lowman in his book "MAGIC: the Untold Story" reports that the primary justification for the Japanese-American relocations and internments was to protect against espionage and sabotage, because Magic could not be mentioned during the war. Those defending the decision to evacuate and relocate when seen in context, notably blogger and investigative reporter Michelle Malkin, point to Magic intercepts as partial justification for EO 9066. Malkin cites 1984 testimony of the Undersecretary with the most Magic knowledge, who stated that Magic "was a very important factor" in their considerations. Extensive additional primary source documents are cited in Malkin's book "In Defense of Internment" to argue that Magic intercepts discuss the development of a spy ring among Japanese Americans by the Japanese consulates, provide the type of espionage data being sent to Japan, and much more which raised a suspicion that many thousands in the Japanese American community were an espionage risk, including members of Kibei, Issei and Nisei.
