CATCH-ALL Revisited

From an important new Jane Mayer piece:

When Binney heard the rumors, he was convinced that the new domestic-surveillance program employed components of ThinThread: a bastardized version, stripped of privacy controls. “It was my brainchild,” he said. “But they removed the protections, the anonymization process. When you remove that, you can target anyone.” He said that although he was not “read in” to the new secret surveillance program, “my people were brought in, and they told me, ‘Can you believe they’re doing this? They’re getting billing records on U.S. citizens! They’re putting pen registers’ ”—logs of dialled phone numbers—“ ‘on everyone in the country!’

(Our insights went even further - scarfing everything - is still too hot for anyone else but SMC to have discussed.)

Aid, the author of the N.S.A. history, suggests that ThinThread’s privacy protections interfered with top officials’ secret objective—to pick American targets by name. “They wanted selection, not just collection,” he says.

...

Binney, for his part, believes that the agency now stores copies of all e-mails transmitted in America, in case the government wants to retrieve the details later. In the past few years, the N.S.A. has built enormous electronic-storage facilities in Texas and Utah. Binney says that an N.S.A. e-mail database can be searched with “dictionary selection,” in the manner of Google. After 9/11, he says, “General Hayden reassured everyone that the N.S.A. didn’t put out dragnets, and that was true. It had no need—it was getting every fish in the sea.”
