No, we don't have answers to those questions.
Here's the timeline laid out by Jim Angle on Fox News tonight:
1. Berger reviewed docs. Sometime later, archive personnel realize some docs are missing and they call Bruce Lyndsey.
2. Berger returns docs, but THEY ARE DIFFERENT DOCS than the ones the archives had noticed. They begin carefully numbering the docs he's given.
3. Berger continues to visit the archives and they discover he takes more documents. They contact the FBI.
That's how Jim described it.
[BTW, Berger isn't talking...his lawyer is. And only because the story leaked. Berger hasn't even been questioned by the FBI yet...not a good sign for him.]
My point is why is the attorney admitting to anything, unless there has been some kind of plea agreement made....Berger was filmed/caught in the act?
Most attorney would admit nothing. "innocent until prover quilty....etc" and advise their clients to plead the 5th,
Why volunteer information, unless you already have an agreement...."I'll admit it, take a lighter sentence, in exchange for the "BIG" fish....or fishes.....or hillbillies....or???
