CPO SPARKEY IS TAKING ME, and more particularly Eric Muller, to task for criticizing the internment of Japanese-Americans in World War II. (He has updated posts here and here.) He says that MAGIC decryptions gave the authorities reason to suspect a lot of Japanese spies and saboteurs, and provides some excerpts.

This is news to me, but of course the last time I paid close attention to this subject, the MAGIC decryptions weren’t public. (MAGIC was, but not its results). It’s interesting, but I’m not sure how this supports Rep. Howard Coble’s statement that the purpose of the internments was to protect Japanese-Americans from mob violence.
