I am wondering. The FBI/DOJ is stating Trump had top secret documents. Now, I dont know how this works but. If he has clearance what is the issue? If he has the proper clearance and has already had the secure location verified, what exactly is the crime? I dont see one. All I see is the DOJ/FBI playing town crier "He has secret stuff!!" Ignoring the idea that he has clearance to have them.
I am also wondering, if these documents are soo sensitive. Why are run of the mill FBI agents now in posession of them when they dont have clearance for it?
Who is going to go break down the FBI's doors and get the top secret stuff out of their hands before an agent sells to the highest bidder?
Lots of super classified stuff is supposed to be kept in safes or not leave a classified room. So bringing them home can get you in big trouble. I know people who ended up paying rediculus fines for bringing work notebooks home.
Any truly classified material would be stored in an approved safe (big filing cabinet with locks) or a SCIF (basically a walk-in vault the size of an office). Any unclassified material can be stored for secure control and convenience. Trump would have been aware of this. You don't get security briefings without this being hammered into your head.
