It's now becoming pretty clear why all the redactions and slow walking of FISA and everything else.
The principals at DOJ/FBI must truly believe that carrying out their devious and illegal political operations are "national security" responses to the current administration, with whom they disagree.
The sources and methods they say they're protecting through redaction are political sources and political methods. That's their new work and their new M.O.
No surprise there, political ops are as old as mankind, but it's hardly "classified." Unless you are them and living in their strange and twisted world.
