You know, I’ve actually thought about this. too. I am no longer together with my now ex-girlfriend, but even at the height of our problems, I never thought it would be ok for me to spy on her — not just because I thought it would be inappropriate, but the paranoia would be mind-destroying. I didn’t even like looking on her Facebook page. It was too weird.
Granted, security issues on a geo-political scale are different from my personal life, but I’ve definitely wondered at the mental damage on a governmental scale that almost limitless spying abilities could cause.
