"If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him." -- Cardinal Richelieu
Privacy protects personal dignity, not just illicit behavior. We close bathroom doors, keep journals, and have intimate conversations not because we are breaking the law, but because we value personal modesty and boundaries.
We are quickly approaching a time when we are all guilty until proven innocent by voyeuristic power-hungry psychopathic megalomaniacs who cry the old cry of "If you've got nothing to hide, you've got nothing to fear"
I do not disagree with the intentions of the quote, however it is disputed.
