I think that this is an important question. We're talking about the largest, 
most well funded defense organization in the world (that we know of) allowing a 
peon to get away with large amounts of highly classified information. Is it 
possible that he was deliberately allowed to get away with it? If so, what 
purpose does that serve and to whom? 
If not, how/who does it serve to release the documents otherwise? Is it simply 
to sell papers? 
Or is this all an elaborately well played ruse to create an excuse for 
referencing further down the line when they finally decide to crack down on the 
internet in America?

So how does knowing about the NSA spying help the rest of us and has it been 
exposed to serve some one elses purpose. (?)
