Employees of the Department of Homeland Security (an Orwellian name if there ever was one) have been warned not to read on an unclassified machine an article in the Washington Post because a slide shown in the article is one of the classified slides revealed by Edward Snowden.
Here is the slide that appeared in the paper, so DHS employees should avert their eyes.
If you work for the Department of Homeland Security and have now seen this slide, call the guys from Men in Black to erase your memory.
This slide is one of a set of nine slides used at an NSA presentation that reveal how the NSA data gathering works. What is interesting about these top secret slides is how they describe the NSA and the major Silicon Valley and telecommunications companies as having a cozy working relationship with each other, sharing information freely.
