But normally the bag shouldn’t be taken out of the building at all. Is that correct?
I worked around classified material for 33 years. Typically, it stays in a building unless it’s destruction time. You bundle it up in boxes or brown-paper bags (heavily marked), and then you go to the shredder in the building, on the post, or in the region.
In Panama, we had a burn ‘stove’....out-door situation where you walked up and cranked up the gas system and the fire started, then we threw the bags in...opened a beer or two...and stood there for an hour while the bags all burned down.
In the Pentagon, we had a team which would collect all the bags once a month and trolly them to the ramp where they’d be loaded on a truck and driven to some central burn building in the Arlington region.
In this case....she has one single bag or packet. Why only one? The only thing I can think of is that she was at Hillary’s residence in DC and she kept a safe there with some materials. Maybe she was cleaning out the safe for Hillary.
