I think the crux of this matter is the 'theft' by a Civil Servant.

The majority of, if not all, Civil Servants (Government employees) are bound by the Official Secrets Act to not reveal secrets and certain information to the general public.

Theft is a crime in any occupation.

To entice a Civil Servant to steal secret documents is doubly wrong.

Of course, a lot of the information the Government keeps secret can be considered by some to be morally wrong, so its revelation to the general populace would be a good thing.

Two wrongs do not make a right though. There are ways to 'blow the whistle' but they should not include theft.
