Teacher of mine spent almost 20 years getting access to his FBI file through FOIA requests. Apparently it was surprising how much of his life they didn't know about.

Children with no life have never had anything worth keeping private. Even the question of having nothing to hide is foreign if you've never done anything at all.

It's like that parable about God giving us free will. If or when the intelligence agencies manage to create a generation with nothing to hide, what will their purpose be? You might as well take field notes on birds or sheep.
