Murdoch's paper has a new article saying the NSA has access to 75% of all Internet traffic. Their editorial board will have to write an editorial condemning themselves... I'm not commenting on the content of the revelations so much as on the fact that the WSJ is a surprising source for information like this, at this time. No indication they got any of this from Snowden, and it's entirely possible this information was leaked with approvals, even if/though the information is classified. But I doubt MI6 will be detaining any NewsCorp reporters who venture through Heathrow...
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.
