The big question I have about the LOVEINT thing is how confident they are that people haven't got away with it. The government have been spinning it as "rare", but what if it's only people getting caught that's rare?
Their auditing sounds weak. They seemed to have no idea what documents Snowden had taken.
While I don't have the source handy, I read recently that most of these LOVEINT "discoveries" were actually caused by the people admitting to it before a polygraph test
