It certainty is a question of what is being accessed. I don't care if it is god damn Mr Rogers with the best intentions. The more sensitive the data, the stronger roadblocks need be in place. Often to the degree of impossible to access because it shouldn't be gathered in the first place.

There will always be good reasons to access data, and sensitive data. There is always good that can come out of this. But just because you can do something good with it doesn't mean you should. You can do a lot of good with a nuclear bomb, but I don't want any ever built because it takes only a small mistake (not an act of malice!) to have huge consequences. There is always a cost, you must always consider if the costs are worth the benefits.
