How should Christians think about PRISM?

When news broke last week about PRISM, the National Security Agency's huge data-mining program, I wondered what the Bible might have to say about privacy. 

Turns out the exact word occurs only once in the NRSV, in Sirach. "Private" comes up 24 times, usually as a gloss on idiomatic expressions. Scripture writers seem to have had the idea that some rooms were not meant to be seen by everyone, some conversations not meant for everyone's ears. But they lived in a tribal world, and the concept of “a right to live one’s life 'screened from public observation'” doesn't seem to have occurred to them.

I learned this using a searchable Bible site. The record of my search is now stored on a Google server somewhere. Presumably, no spy agency is interested in my Bible reading. But it would be easy to add a bot to track user information at that site or just about any other.
