97 months in jail for taking home classified information.
This guy turned himself in after having secret information on his electronic devices. Two years probation, a $7,500 fine and permanent loss of his security clearance.
Asia Janay Lavarello was working on her classified thesis in a SCIF, but when Covid shut it down she took documents home with her to finish her thesis. She had a dinner party and a guest noticed the documents and reported her. She returned them two days later, but got three months in jail and a $5,500 fine anyway.
Admittedly, jail time is fairly rare unless there are extenuating circumstances, but not unheard of. Much more likely is being fired and losing your security clearance, or receiving a fine and loss of clearance and job.
