Actually, I think what the sentence below illustrates is that a single scenario 
can represent both security and privacy problems. The key to identifying them 
seems to me to be about expectations...

- if I expect that by using TLS and "nice long keys", I can keep my 
conversation secret from the government for 5 years, and they crack it in 5 
minutes, then there are clearly some issues with my assumptions about algorithm 
strength; I'd classify that as a security problem.

- if I expect to be able to have a conversation without the government 
listening in, and they can and do listen in, then that's a privacy problem.

In other words, the same scenario can be both a security and a privacy problem, 
depending on the perspective from which you look at it.
