Britain's top counter-terrorism officer has quit after mistakenly holding secret papers towards news photographers.

Clearly this was a breach of secrecy. But, it made me think that people send unencrypted emails all the time, and these are just the same as walking around with a document on view to the world. You never see a story about top secret information being sent by unencrypted email, probably because it isn't so easy to comprehend. An unencrypted email goes through third-party infrastructure, and mail servers, and could be logged or read at any point.

At least there is a nice "physical world" analogy now.
