Re: who in the first place?
NSA back door on the military.... I don't think they need to bother with that one. I'm sure they had access to everything I knew, everything I did, and everything in my service record, when I was in the Navy. Well it wasn't called 'NSA" back then but same idea.
[on a related note, there is still some classified information I won't disclose knowledge about, nor discuss, because it hasn't been made public knowledge, even from 30+ years ago].
