My two cents are it's confirmation E.O. is incoming. Barr is an institutionalist. I think he was happy to help Trump out some, keep the DOJ from collapsing, and wants to get the hell out before E.O. invoked and he has to take some real historical heat for being a part of it.
"If your work must be done in darkness the goal doesn't belong to the light."
Most of our liberal adversaries are naturally useful idiots. They truly believe in globalism because they are naive to evil and human nature. As such they become complicit in that same evil. Perhaps if they could see that anything that has to be done in secret is by definition wrong a few of them could be saved.
That is all
The reason we've all been frustrated and had blue balls for 4 years is because of the key element of all good illusions distraction. What if Trump wanted all of us, and more importantly ALL OF THEM thinking about Russia/Flynn/Hunter/Impeachment/Taxes so that he could spend the whole time setting up the greatest election trap of all time. Lull them into a false sense of security and all that shit.
Old bagpipe Barrs actions tonight got me thinking. Maybe not true, but at the very least "cool story bro".
