Everything is now stored on computer. Even your personal info. A gubmint computer.
In my enlisted years, I was an intel specialist. No way we’d leave documents lying around for other to look at.
This is the same thing for the computer era. If it’s classified, then it’s under lock and key until an authorization comes down for it to be reviewed on a case-by-case basis. There’s no acceptable reason why that still isn’t the case.
