I agree with you.
That said, this statement is at odds with your statement in regards to lying.
> The filing described Mr. Martin as computer genius who easily outsmarted government efforts to protect secrets and said he possessed an advanced understanding of how to encrypt messages and hide information in cyberspace.
They are certainly lying in terms of how capable he was with the "genius" implications.
The simple truth is NSA internal security is fucking terrible as we are shown time and again that lone wolves are easily able to do this if they so choose. Snowden isn't some magical computer genius of exceptional ability either. He honestly comes across as more of an above-average (but not 1 in 100) IT guy.
I'm willing to bet Martin is "above average" but, once again, not a computer genius mastermind capable of outsmarting competent security practices. It is simply the NSA is not competent at implementing such practices when it comes to internal actors.
