In the UK, we aren't having any real public debate about the security services, largely because the homegrown news organisations aren't giving the issues the attention they deserve. I don't know what would happen to them if they took a stand against a D-Notice.

(BTW, the 2nd result on that BBC news search is more like a job ad for GCHQ)

(Edited to remove my erroneous claim that D-notices aren't voluntary, turns out they are, though hardly any media orgs. go against them)

Guess I should have been more specific, it is an official D-Notice by the MOD relating to Tempura:
