The Sealed Circuit

The EFF had done the hard work. They'd found Mark Klein, a former AT&T technician who'd watched engineers install a secret room at 611 Folsom Street in San Francisco. Room 641A. Fiber optic splitters wired into AT&T's backbone, feeding a full copy of essentially all internet traffic into NSA hardware. Klein had the technical diagrams. The EFF had the lawsuit — Hepting v. AT&T, filed January 31, 2006, a class action on behalf of every AT&T customer whose communications had been quietly cloned for government review.

The government's response, filed April 28, 2006: State Secrets Privilege. Translation: we can't defend ourselves in court because confirming or denying any of this would harm national security. The lawsuit must be dismissed.

Notice the move. The administration didn't argue the surveillance program was legal. They argued it was too secret to litigate.

The State Secrets Privilege dates to a 1953 Supreme Court case, US v. Reynolds, where the Air Force invoked it to suppress evidence in a crash lawsuit. Decades later, when those records were finally declassified, the real reason became clear: not national security, but negligence. The evidence would have won the plaintiffs' case.

Pattern recognized. Filed away somewhere. Apparently unused.

Room 641A was the physical instantiation of something the tech industry spent the next two decades pretending wasn't happening: the seamless merger of commercial infrastructure and the surveillance state. AT&T didn't get invaded. They cooperated. Someone with a badge asked someone with a contractor relationship, engineers installed the splitters, and traffic flowed both ways — to users and to Fort Meade.

The legal machinery that followed was just the circuit completing itself. State Secrets Privilege invocation. The 2008 FISA Amendments Act, which retroactively immunized the telecoms. The eventual dismissal of Hepting. The EFF refiled as Jewel v. NSA and watched that case spend fifteen years being killed by the same privilege. When the Snowden documents surfaced in 2013, they confirmed everything the government had said was too secret to confirm.

The template isn't complicated. Build surveillance into the infrastructure at the infrastructure layer. When caught, invoke the legal mechanism that converts court proceedings into a national security event. Legislate immunity for the companies afterward. Repeat.

"Too sensitive to litigate" is a strange phrase. In practice it means: the facts, if established, would be damaging enough that we'd rather not have them established. The sealed circuit protects itself by sealing off the proceedings that would reveal it.

Somewhere in a secure facility, someone thought this was elegant. They were right, in the same way a bug that prevents its own detection is technically impressive.

The EFF is still litigating variations of this fight in 2026. I'd say I'll start the timer to the next privilege invocation, but honestly the timer never stopped running.
