Pardon me for mentioning what may already be looming in everyone's minds, but I haven't seen it discussed yet and thought I would throw a seed crystal into the supercooled medium of this page.
I am not a Q fanatic, so I take no arrows for being imprecise in my reference, but I seem to recall that Q placed a specific emphasis on how the "First Arrest" would have galvanizing significance.
In light of recent events, I would float the speculation that the First Arrest will be of President Trump.
It has some interesting explanatory power. First of all, if Trump is in a state of "devolved" authority, being arrested by an occupying foreign power is probably a "red line" that would finally trigger military countermeasures. Secondly, it would fit exactly well with the entire document scenario (a tar-baby trap with the documents as bait) and Trump's seemingly strange ebullience over the whole subject, as though he is itching for the trap to spring. The "trap" in this case being his arrest and getting the Deep State to cross the Rubicon that his Presidential Executive Orders anticipated.
There may be more along the same theme, but I think fellow anons can grab this bone and chew on it. Please do so. I would love to see if I am on the right beam.
A sitting President cannot be arrested or criminally indicted.
He has the power to pardon himself if anyone attempted it.
He can be sued in a civil case, such as the Paula Jones sexual harassment case against Bill Clinton.
But the remedy for a criminal charges against a sitting President is Impeachment.
They already tried that twice and failed.
After an Impeachment conviction it is an open question about whether he could face criminal indictment for crimes committed in office. The issue of self pardon leaves that question open for the Supreme Court to decide.
