They have been doing it for decades.
Rudy Guiliani was one of the first assholes to threaten multi-decade (or century) prison terms in exchange for a guilty plea.
Piece of shit.
Either you have the evidence to prove your case, or GTFO.
We all have stem cells in our bodies. They hang out on the edges of cells, and can turn into whatever type of cell that the body needs.
Think about it like this:
Q has implied (though not acknowledged directly) that Mueller is on Team Q.
If it turns out that was not true, it would diminish Q's credibility in the minds of normies.
But just imagine …
What if Mueller does a 180 on everybody and somehow supports Trump and/or incriminates Hillary, Barry, and the entire cabal?
In the mind of the normie just discovering this "Q thang," such a development would boost Q's credibility via past drops (future proves past) like nothing else could. It would almost overnight crush any credibility that fake news still had left.
