We recently published a one-page document summarizing the evidence that is the centerpiece of EFF's Hepting v. AT&T case. Information for the document came from previously secret evidence that was unsealed this summer, including the declarations of whistleblower Mark Klein and EFF's expert witness, J. Scott Marcus, a former Senior Advisor for Internet Technology to the Federal Communications Commission. The document includes the following diagram, a straightforward illustration of how a massive portion of innocent Americans' communications were put under the control of the NSA:
For those who haven't already seen it, the PBS Frontline documentary "Spying on the Home Front" explores the evidence in clear, concise detail. The 10-minute portion that strictly covers the evidence can be found here, but you can stream the whole documentary for free and without DRM from the Frontline website.
