The intelligence agencies insist you must choose: either they collect everything on everyone, or they go blind and the country is unsafe. Privacy or security, pick one. That choice is a lie, and a former senior NSA official proved it before 9/11.
William Binney was a Technical Director at the NSA - one of its most senior code-breakers. In the late 1990s, he and his team built a signals-intelligence system called ThinThread. It could ingest enormous volumes of data, find the genuine threats, and discard the noise. And it had a feature built directly into the collection mechanism: the moment it swept up the data of an American, that person's identifying information was automatically encrypted - turned into a token that could not be traced back to a real person.
To unlock it, an analyst had to take probable cause to a judge and get a warrant. The Fourth Amendment was not a policy someone could choose to ignore - it was hard-coded into the software itself. Effective intelligence and protected privacy, at the same time, by design.
After 9/11, NSA leadership stripped the privacy protections out and went with a different approach - the warrantless mass surveillance the country has lived under ever since.
Binney resigned. His home was later raided. But he was never charged.
It's time to adopt the principle Binney already built. Tokenize the identifying data of Americans at the point of collection, and require a warrant to detokenize it. The capability to find real threats stays. The ability to unmask an innocent American without a court order disappears.
