They have to communicate in some way. I'm amazed at how much is said as if the speaker actually know what went on in the NSA spying when a) all the info known is from the news that broke it, which indeed said that the spying was on international calls trying to get signs of terrorism, and b) everything else is classsified and unknown except to the spies themselves. Saying it was done to everyone, or that they were up to no good, is pure speculation at this point. The facts known don't point to any of that. Of course it's sensitized, of course it's what was leaked by NSA employees, but you can't just assume what isn't there. And Martin Luther King jr. was far more effective than Malcom X.
