If I tracked 100% of people's activity, professional, sexual, recreational, intellectual, physical, I'm sure an anecdote would arise where someone didn't go to jail because we all had this information to prove he was innocent. I hope you're seeing how this isn't very relevant however to the question whether we want this kind of monitoring. I also don't see how your anecdote in any way is a long story for 'it doesn't hurt to keep that kind of data'. It's a story for how 'it can be helpful to keep that data as shown by one particular anecdote'. That's not really the point, I think we all agree we could find a useful application with data, the point is that we may not want these things to be monitored for opposite reasons.
