Not a D notice
On a point of information, my understanding is that this was not a D Notice. It was a one off agreement hammered out via the Editors' organisations. The UK media adhered to it as did all of the European press that learned of it.
Drudge brands himself as a citizen journalist - the sort of reporting that appears on this website, so when you lambast 'journos' consider yourself one, if you have ever posted a 'rumour' on PPRUNE.
On a smaller scale journalists regularly adhere to restrictions on what they divulge not just with the armed forces, but with police investigations etc. Not just most, but the vast vast majority of UK journos are highly responsible when it comes to such requests in my experience. Believe or not. (Not, I suspect).
