Ex-wife criticizes Nelson Mandela – and many South Africans agree

“In order to get access to the actual cables, NSA had to build secret rooms in these buildings (telecommunications companies). So what would happen would be the communications on the cables would come into the building, and then the cable would go to this thing called a splitter box, which was a box that had something that was similar to a prism, a glass prism. And the prism was shaped like a prism, and the light signals would come in, and they’d be split by the prism. And one copy of the light signal would go off to where it was supposed to be going in the telecom system, and the other half, this new cloned copy of the cables, would actually go one floor below to NSA’s secret room. So you had one copy of everything coming in and going to NSA’s secret room.

In the secret room was equipment by a private company called Narus, the very small company hardly anybody has ever heard of that created the hardware and the software to analyze these cables and then pick out the targets NSA is looking for and then forward the targeted communications onto NSA headquarters.

... This company, Narus, which was founded in Israel and has large Israel connections, does the—basically the tapping of the communications on AT&T. And Verizon chose another company, ironically also founded in Israel and largely controlled by and developed by people in Israel called Verint.
... Through these two companies (Verint and Narus) pass probably 80 percent or more of all US communications at one point or another... these companies also supply their equipment all around the world to other countries, to countries that don’t have a lot of respect for individual rights - Vietnam, China, Libya, other countries like that. And so, these countries use this equipment to filter out dissident communications and people trying to protest the government. It gives them the ability to eavesdrop on communications and monitor dissident email communications. And as a result of that, people are put in jail, and so forth.”
