In the Reply Letter from Defense Intelligence Agency, it is said that "Mr. Eftimiades wrote his book, Chinese Intelligence operations, at home, using his own resources. He conducted his research using his own funds. His research included only publicly available sources, persons as well as documents. ..." If we can prove he was using offiial time, official fund, official resource... , then we can say Mr. Eftimiades needs get Government permission before he make any noise and he did not.
