How about trusting that a POTUS can never mishandle classified documents from his tenure or before? Or raise the burden of proof from merely “mishandling” to literal subversion or treason. Beyond a reasonable doubt.
Not to mention the problem of over classification. Anything that is mildly embarrassing to anyone with the ability to gets it classified.
Do they really have to write rules like, “Don’t leave top secret information in haphazard stacks in your son’s garage unless you want him to sell that information to support his coke habit”?
Comey was a good example...after meeting with Trump, in his car, he typed the results of their meeting...and then classified it. He was sure he had a "gotcha" he could use against Trump.
