More on NSA Data Collection
There’s an article from Wednesday’s Wall Street Journal that gives more details about the NSA’s data collection efforts.
The system has the capacity to reach roughly 75% of all U.S. Internet traffic in the hunt for foreign intelligence, including a wide array of communications by foreigners and Americans. In some cases, it retains the written content of emails sent between citizens within the U.S. and also filters domestic phone calls made with Internet technology, these people say.

The programs, code-named Blarney, Fairview, Oakstar, Lithium and Stormbrew, among others, filter and gather information at major telecommunications companies. Blarney, for instance, was established with AT&T Inc….
This filtering takes place at more than a dozen locations at major Internet junctions in the U.S., officials say. Previously, any NSA filtering of this kind was largely believed to be happening near points where undersea or other foreign cables enter the country.

The systems operate like this: The NSA asks telecom companies to send it various streams of Internet traffic it believes most likely to contain foreign intelligence. This is the first cut of the data. These requests don’t ask for all Internet traffic. Rather, they focus on certain areas of interest, according to a person familiar with the legal process. “It’s still a large amount of data, but not everything in the world,” this person says.
The second cut is done by NSA. It briefly copies the traffic and decides which communications to keep based on what it calls “strong selectors”—say, an email address, or a large block of computer addresses that correspond to an organization it is interested in. In making these decisions, the NSA can look at content of communications as well as information about who is sending the data. One U.S. official says the agency doesn’t itself “access” all the traffic within the surveillance system. The agency defines access as “things we actually touch,” this person says, pointing out that the telecom companies do the first stage of filtering.
The surveillance system is built on relationships with telecommunications carriers that together cover about 75% of U.S. Internet communications. They must hand over what the NSA asks for under orders from the secret Foreign Intelligence Surveillance Court. The firms search Internet traffic based on the NSA’s criteria, current and former officials say.
The NSA seems to have finally found a PR agency with a TS/SI clearance, since there was a response to this story. They’ve also had a conference call with the press, and the Director of National Intelligence is on Twitter and Tumblr.
I am completely croggled by the fact that the NSA apparently had absolutely no contingency plans for this sort of thing.

Why are you croggled given everything you’ve written post 9/11? The government clearly stinks at risk management.
