Going on spreading interesting documents in whatever the language they are, I found this one clear enough to explain how easy and how banal spying turned to be. So anyone is able now to spy his neighbor, his wife and sky is the limit. Even the financial aspect of getting an affordable but correct device has faded away. You can find out under $10 tiny video cameras, some of them embedded discretely within a pair of glasses. And we're just at the very beginning of the likely to come collapse of privacy. Could we call that a progress? Yes if you are a dealer of such apparatus, definitely No il you have some responsibility for the future of young generations.
