So... I wonder what the 4 page memo said.
It is a summary of true events, confirmed suspicions and added a handful of new conclusive evidence, as well, with all four pages attached to hard copies of documents, both classified and non-classified, to back up the summary.
The caution is to protect the classified memo in order to save what is classified, for use in penal charges. Anything mistakenly released can not be used in prosecution. Reportedly.
You don't know the context. Plus the citizens are too dumb to understand it.
BTW - haven't heard much about McCain recently. Things can go very quickly with what he has.
There was a hint a few days ago that basically stated that one example we will see is that known Clinton advisors and known Clinton cronies falsely authenticated the dossier to fisa court so that Obama could spy on Trump. People like Sidney Blumenthal
