How are SEC whistleblower protections relevant to the NSA?

As for the Pentagon, you'll note that part of what it covers is that the Pentagon Inspector General has struggled to substantiate allegations of retaliation in most cases, to the point where they ended up resorting to introduce a new system of mediation to resolve cases. Maybe that's because the allegations were bullshit, or maybe that's because the system is totally without teeth. In either case it does not illuminate the case of Snowden at all.
