He isn't saying anything anyone else hasn't already thought about. His problem is he is saying it from a position of authority, which gives the accusations more credibility, if not certainty. He should not be grouped with other persons that willfully leak information, i.e. Wikileaks. Those organizations are leaking potential sensitive information, regardless of whether or not there will be follow on effects.
He has simply stated what the government should already have been transparent about.
Where I disagree with him is the supposed likelyhood that your past information will be used against you, even if you're a good person. While this is certainly possible, your everyday person committing petty crimes will still remain at the bottom of the priority list. In fact, I believe that list will only become longer and more detailed, pushing petty crimes even further down the list.
