The Docs AT&T and the NSA Don’t Want You to See

The whistle-blower in the AT&T domestic spying case submitted three documents as evidence to the court. Both AT&T and the NSA have tried to prevent these from going public, but here they are.

Former AT&T technician Mark Klein is the key witness in the Electronic Frontier Foundation’s class-action lawsuit against the telecommunications company, which alleges that AT&T cooperated in an illegal National Security Agency domestic surveillance program.

In a public statement Klein issued last month, he described the NSA’s visit to an AT&T office. In an older, less-public statement recently acquired by Wired News, Klein goes into additional details of his discovery of an alleged surveillance operation in an AT&T building in San Francisco.

Klein supports his claim by attaching excerpts of three internal company documents: a Dec. 10, 2002, manual titled “Study Group 3, LGX/Splitter Wiring, San Francisco,” a Jan. 13, 2003, document titled “SIMS, Splitter Cut-In and Test Procedure” and a second “Cut-In and Test Procedure” dated Jan. 24, 2003.
