Does not matter how the documents got into her possession. Possession itself is punishable - when it comes to various clearances and who has seen or has possession is very serious and no one fools around - there are no innocents.
If her server and email account has such documents on them, then she is in violation for each offense, and answerable to various federal codes all of which include prison time, and one which bars her from any federal office.
All of this looks very bleak for her, but to most LIVs this is in the weeds and can be dismissed. Its not like she B-slapped Kim Kardashian or something horrible.
Her team is busy making sure that rule changes at voting places are changed to allow maximum voter fraud, so any possible recriminations will not amount to a hill of beans - no pun intended.
Besides if she were imprisoned or lose the election there is the matter of hundreds of millions of dollars “donated” to her foundation in lieu of future policies which would have to be paid back. It could turnout that the safest place for Hillary is in some max security wing of some Federal prison ...
I would suggest that there are those that might decide the best place for Hillary is a grave. She can be interviewed in prison. Being the vindictive bitch that she is, no telling what truths or lies might emanate from the prison
I have posted before that a stroke will do her in and off the stage forever
