As I said, it's entirely possible that the Emperor kept the FDS limited to very specific information outlets -- himself, mostly -- and they didn't feel strongly about doing some spywork.
Like if the Emperor doesn't let you talk to professors at all how are you supposed to learn the history? What if the databanks he gives you are chock-full of self-aggrandizing material?
It might speak to a lack of initiative on the FDS' part about sneaking out of the Embassy and "go" areas to get the truth but in an autocratic society where our Embassy is right under the nose of the Emporer, it is not totally unreasonable they were working with limited information.
