I live in a military community. I have personal examples to site. If you are careless with classified material (either electronic or paper) you are in the wrong. Whether this is through intent (like a spy/traitor type situation) or by accident (inadvertently sent something...cleaned up your desk to take stuff home and you accidentally took something) you are in the fault.
Service men and women are routinely punished (significantly) for an honest mistake.
She should be no different.
