You don’t understand what I’m talking about, because you have an inherent misunderstanding of the issue at hand.
Donald Trump is under criminal investigation for taking national defense information. National defense information is paid for by the taxpayers, it is owned by the United States government. Donald Trump has no right to take what is owned by the American government. Even declassified, a document doesn’t become the possession of the person who declassified it.  It is still owned by the government.
You agree with this. Declassify does not mean “to take ownership or possession of”. 
So instead of just saying “he declassified them”, why don’t you try explaining how Donald Trump took lawful possession and ownership of something that is paid for by the American taxpayers.
Because declassification isn’t that process.
