In fact, it's almost tragic. We demand a perfect security which is getting ever harder to achieve. Civil liberties groups, for very honourable reasons, create technology for the good guys, and it gets abused by the bad guys. When our security services don't succeed (and they can't all the time), we consider them useless, because we imagine them to be monitoring everything. But if they do succeed, they are "Orwellian," if we even see or hear what they're doing. My owrry is that if we carry on as we are, we'll end up with intelligence agencies which are seen as both omnipresent and incompetent - which lack broad public support, but also cannot do their jobs. This is the precise opposite of what we want.
