Yeah this way, anyone which cleans these people’s homes have access to these documents.  I’m positive at least a few secret documents have gone missing without anyone noticing.
My take:

They need to create separate classifications to those documents which are office bound and those that are transportable to be returned. The ability of our senior leaders to do their jobs has to be considered too. >

Agree, but still think there is a big difference between inadvertently taking a few documents and intentionally carting off several crates worth of files. >

Top Secret documents should be loaded onto GPS trackable electronic tablets.
The tablets should be secured and their contents wiped once no longer needed, reported stolen, tampered with, or expired. >

You would think they would learn from the private sector. I can't access anything at work unless it's from my company computer. After I've logged in with MFA. 
A secured tablet would make more sense than shifting around paper. Plus any classified documents that are created on the fly (meeting notes, call notes) are already secured.
