So the ADA takes the fall, loses her job and her entire reputation as a diligent long-term prosecutor, rather than privately say to her boss (once the scandal hits) "please call the CIA and discuss this case before you summarily trash me in public and cost me my career"?Because that's how she'd have to behave to get to this point. She took the fall rather than point the finger at someone else (e.g. our government).
So who's she so afraid of? Our guys who got her fired? No way. A long-term U.S. prosecutor, especially a female, is in no way, shape, or form going to "fear" our guys enough to lose her career with nary a word.
And our guys don't go to bat for her and either convince her boss to keep her on or at least set her up in a nice cushy federal job?
No way.
The "our guys did it to her" argument loses in two completely different ways: 1., it loses because she's quiet after getting burned, and 2., it loses because she didn't get set up in a cushy federal job for playing ball with the big boys.
But the scenario that fits the available evidence is that she got burned by the bad guys, and they aren't sticking around to give her some nice cushy private sector job in the city of her choice.
And that's not to even say that she realizes that the people who "talked" to her were indeed bad guys. It could have been a sob story from one "professional" prosecutor to another (as role-playing/acting is a popular strategy for spooks).
Whatever made her make that decision, it was powerful enough that she isn't talking about it.
Get that ADA to talk and you've got yourself a link to a foreign cell here in the U.S., even if it is nothing more than a criminal police-sketch of what one of them looks like.
