More slides shows light on how the NSA has access to your information on facebook, google, yahoo, etc.

The top-secret PRISM program allows the NSA to gain access to digital information on nine internet companies including: e-mails, pictures, and other stored data of the website users. The program is court-approved but does not require individual warrants. Instead, it operates under a broader authorization from federal judges who oversee the use of the Foreign Intelligence Surveillance Act (FISA). The Washington Post released some documents describing the slide. The
newly released documents below give additional
details about how the program operates, including
the levels of review and supervisory control at
the NSA and FBI. The documents also show how
the program interacts with the Internet companies. These slides, annotated by The Post, represent a selection from the overall document, and certain portions are redacted.
