Since 911 the world has changed. There are thousands of conspiracy theories on how 911 benefited governments around the world to implement new laws enabling them to spy on their citizen without even needing a court order.
There are billions of phone conversations, emails or text based chats taking place every day on this planet. The National Security Agency (NSA) is using facilities like Echolon to intercept and evaluate communications between individuals.
The real challenge the NSA is facing that there is too much data to be evaluated manually. Many people think that certain keywords e.g. “bombe….” would trigger a manual review. Actually it would not trigger a review. Suicide bombers might not be the smartest people on earth, still they are smart enough to be aware of that their communications could be intercepted. It’s very popular with terrorists to use code words to keep their communications secret from outsiders.
How can the NSA evaluate so much information?
