Why yes they can, and have been able to do so for a while. Is this somehow new and shocking to you?I never said they were monitoring every single mouse click or email, I'm stating, like the facts represent, that they CAN check any given individuals email, browsing history, phone calls, etc. They also DO this on a very regular basis with almost zero oversight or approval required. As the leak reported, any authorized low level employee can use the software without specific authorization for the person they're looking for.
It takes more than that to make the list. As of 2008, there are over 3.5 million Arabs in this country. They aren't going to watch them all. They would be looking for behavior, aliases, associates, religious and political views, and other things like that. They would have a system that helps them sift through and filter what they view is a credible threat.Combine this with the previous leak, that they're gathering an insane amount of meta data on everything you do, they can target individuals with "suspicious profiles".
(which turns out to be rather silly things like 'using a language not typical of the region they're in.' This is the American melting pot, no ****).
The most wanted man alive is Joaquin Guzman. Snowden isn't even on the top ten list. It was also easily realized if anyone in this ****ing country actually paid attention to what was going on around them. Room 641a, look it up and tell me you wouldn't come to the same conclusion. Or just look at the history of the FBI and the CIA.This is insider information. Up until now the depth of their abilities has been largely unknown, and was mostly viewed as "paranoid conspiracy theories". Now we have definitive proof. If it wasn't insider information, Snowden wouldn't be the most wanted man alive right now.
