I have a large number of old photos of Soviet, UK and NATO ships, Nuclear Submarines and planes all stamped with Restricted and all handed out willingly to crews by the Int department. Those in charge clearly understood that they would be taken off base and shown to families and friends because why else would people need them and why would they be so happy to hand them out? Did they think we all had secure combination cabinets in out houses and locked them away for 30 years? At the same time, I think most people realised that they shouldn't send them to the press or display them on the local village hall notice board (1980's internet).
Common sense semed to be the order of the day but it doesn't seem to be enough these days.
I do remember a mission being delayed for several hours though when a Co-pilot was arested and questioned by the Norwegian Police for taking pictures on a very dull P3 base hundreds of miles from anywhere.
