"the people’s right to know ... is virtually unlimited"

Nonsense. Human relationships are based on trust and respect and not on any "right to know," virtually without limits. 

You have the right to know what I want to share with you, unless you don't trust and respect me with or without a cause.

If it is with cause (for example, I am a threat to others), then you have the right to know as much as that cause justifies. If I do not present a threat, the only right you have is to show trust and respect.

If you do not respect and trust without a cause, then you have a major problem. An unlimited, relentless pursuit of information under the guise of such twisted understanding of "rights" is selfish, self-serving and as such it is dehumanizing and destructive. The fact that you claim this as one of your guiding journalistic principles, says volumes.
