I have been blessed to have a decent clearance with some cool caveats for awhile now. That bolded part makes me want to drown puppies. Seriously? Just write something out.. "I think it's classified, eh.. screw it." The story, while light on details, doesn't even read that way.
Possible options:
She has a journal at home that she filled with classified info.
She took classified docs home.
Are either of those even remotely ok?
Also.. with the rigid requirements for working with this stuff (inline statements, overall statements, etc) how can someone not currently involved with it not know? Additionally, with the pre-publish review requirement... wtf?
Good to know you have a line somewhere.
