No offense, but do government-controlled agencies always stick to what's legal?
Just remember those anthrax-spur infested letters that got sent to officials shortly after 9/11. A few months later it was found out that they had gotten sent by the boss of a government-run lab for biological weapons who was pissed that he had gotten a budget cut.
(No offense to Americans meant! My point is that no control whatsoever can guarantee correctness and legality. There's always the human factor and every system can be abused. It's just a matter of what we over here call "criminal energy". I'm not sure if such an expression exists in English but I think you get what it's meant to express.)
