Stasi couldn’t record what newspaper articles you were reading. For how long. And in what order. That, along with pretty much every thought you have ever explored while sitting at a computer, is now part of your permanent record – even if you never told a single human being.
[..] once you have prevented a murder, it’s easy to justify that you should be able to use the ubiquitous wiretapping to also prevent, say, rape and aggravated assault. No policymaker will protest that.
Once you are preventing serious violent crimes, it’s easy to justify that the NSA and the Police should use the ubiquitous wiretapping to prevent all violent crimes. People who protest that in the name of civil liberties will be shot down; “it’s a fundamental civil liberty to not be a victim of a violent crime”. And so, surveillance will be Newspeaked into civil liberties in televised debates by Big Brother hawks.
Once the wiretapping is preventing all violent crime, it will be repurposed to prevent all prison-time crime (described as “serious crime”), and from there, to prevent all crime. And those who speak up against this will be accused of “siding with criminals”.
