Someone needs to ask Obama why he both backed and co-signed bills that would curb the power of the NSA before he became president, only to completely change his tune afterwards. I've said it before, but I also believe that the NSA now has the power to make sure that presidents toe the line. The question everyone needs to ask themselves is; who's line are they toeing? Who's the piper? Who is the power behind the throne? It might just be conspiracy theory, but the problem is the NSA now genuinely have the capability to do this. Even if they aren't, how would we know if somebody rogue came in to head up the NSA; an American Joseph Goebbels for example. We wouldn't even know, because all of those secret courts and secret policies would hide the reality from the public until it was too late. I just hope that we aren't too late already.
