LARRY PFEIFFER*: I've known several people who have retired, and after they retire, they're going through their box, and it's like, whoa, how did that [classified document] get in here? And they - you know, they call back to the building. Some security officer comes out, picks it up. Everybody's fine with it.
NPR's GREG MYRE: Yeah, that's undoubtedly true. And here's the irony. If you're a junior staffer, the likelihood of mishandling classified records is pretty low. To see that kind of information, you'd go into a secure room at your agency. You'd walk in empty-handed. You get briefed and read some classified documents. Then you walk out empty-handed. You really can't accidentally walk off with documents. But it's easier to make that mistake at the top levels of government.

GLENN GERSTELL**: An official, usually a more senior official who has both unclassified and classified documents in their workspace on their desk.
