WSJ: New Details Show Broader NSA Surveillance Reach

schwit1 (797399) writes "The National Security Agency—which possesses only limited legal authority to spy on U.S. citizens—has built a surveillance network that covers more Americans' Internet communications than officials have publicly disclosed, current and former officials say.

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 NSA's filtering, carried out with telecom companies, is designed to look for communications that either originate or end abroad, or are entirely foreign but happen to be passing through the U.S. But officials say the system's broad reach makes it more likely that purely domestic communications will be incidentally intercepted and collected in the hunt for foreign ones.

For the 2002 Winter Olympics in Salt Lake City, officials say, the FBI and NSA arranged with Qwest Communications to use intercept equipment for a period of less than six months around the time of the event. It monitored the content of all email and text communications in the Salt Lake City area."
