I don't think so. As a person who has ever had access to classified info, even when your access is removed, you still have an obligation (under penalty of law) to protect that information. I think if someone gave you info that you knew you did not have access to, it would be your obligation to report that to a security official.
Yeah, that’s a murky area.
I remember from the Manning and Snowden scandals, that warnings were issued, through the DoD General Counsel to the entire organization, that the information was still classified even of it appeared in the media and that, as security clearance holders, we had not been granted access to it. So you were in the protected but absurd position of saying “ I don’t know because I’m not allowed to read the newspaper, magazine, website, etc. article.” If the same information showed up on your computer somehow, it was “spillage” and you were to immediately to unplug from the network and notify security so your machine could be cleaned. The prohibition was general, so the 2 or 3 of us that actually followed the guidance, still don’t know what was actually disclosed.
About a year or so from now, I’ll be fully retired and essentially in the situation I described: no clearance, no access. It will be the first time since I was 18.
If another Snowden or Brady leak of classified information to public media occurs, is every former clearance holder who reads the subsequent articles liable if they don’t report it?
