Feel free to show examples of said "well-define legal channels" which Snowden could have used to show the depth of NSA's activity as he did, where the discussion is open for public debate.
Also this has been going on for so long, why didn't anyone else from NSA use said well-defined legal channel to expose NSA activity or at-least put them up for scrutiny.
I can think of 3 reasons:
1) There is no well-defined legal channels to expose NSA illegal activity, to the extend Snowden did.
2) NSA only hires people who are morally corrupt.
3) NSA employees are genuinely concerned about their safety and well-being if they want to expose NSA.
