Gosh.
I remember the first day of my communications security classes.
Heres what the instructors told us,
Whether you do it intentionally or unintentionally, if you give away our governments secrets, we will throw you in prison.
My Security training in the service was exactly the same, blueinicorn6.
The instruction was very clear, very plain, and oft repeated: makes no matter whether you intended to, or not, mishandling ANY classified material is a crime, and punishable to the maximum provisions of the law.
It was NEVER a question in my mind. NEVER.
im ww2 loose lips sink ships- death penalty was threatened to communications officers
...and like Hillary, signed documents saying you understood this to be the case as a pre-requisite to being allowed access to the secrets.
