Society IS heading towards collapse, and largely because those deciding what is ethical and legal have no ethics and long ago discarded the legal limits of the Constitution.
If I were a lawyer, I would be salivating to take this case.
Everyone must decide for themselves what is legal and ethical. The bottom line is whether or not what the NSA was Constitutional or not. If it was, Snowden will end up spending life behind bars. If it’s not, then he was doing his duty to support, protect and defend the Constitution.
The question is whether or not they will prosecute him. If they do and he can make a prima facia case that the NSA action was unconstitutional, his ability to subpoena evidence will scare the NSA to death. Eric Holder already wants to keep secret a District Court decision declaring some program unconstitutional.
It should be interesting.
