IMO, there's a heap of jiggery-pokery going on, perpetrated by the spook state, in order to set some predicates.
I don't believe, for a single moment, that Biden was wily and clever enough to have absconded with SCI documents, which are nearly as tightly guarded as Ft. Knox.....For me, that's the tell.....IF those documents were "in his possession", they were almost certainly planted for maximum narrative effect.
To highlight this, note how the media narrative has shifted from the specific of "SCI documents" to the more vague "classified documents", which includes those which have been subsequently declassified, and the far more benign classifications of "secret" and "confidential" -both if which comprise the bulk of "classified" docs and are representative of the culture of over-classification.
IMO, the whole "classified documents" thing -from Mara-a-Lago, to Biden, to Pence- is a big psyop, designed by the spook state, to set the parameters and boundaries for who is "worthy" to run for president in '24.
