National security /is/ about standing up for the people. And yes, that should be closely monitored by journalists, but that does not mean that everything should be public.
Governments are to serve the people and we cannot blindly trust them with power regardless of how they're formed. As long as people continue to subscribe to scaremongering for terrorism, the terrorists have already won anyway. The surveillance states of late have powers blown way out of proportion. They ought to save lives in face of threats, not save lives for retrieval by automated data systems. I have no problems with the former, but I do very much have problems with the latter.
