It's interesting that the Deep State conspiracy theory is
proffered by both the left & the right in Ameristan. It really
became prominent when Trump alleged that the Deep
State was thwarting his agendas, & stole the election.
Yet Deep State fans cannot divulge any of the actors &
detailed plots that pull the strings of state from their
secret lair.
A better view is that politics combined with economics
is a very complex stochastic process. Some people are
predisposed to see the emergent properties as emanating
from a central control that hides itself from view. It's
analogous to seeing the hand of God instead of evolution,
which is another example of highly complex stochastic
processes.
This explains the corruption, incompetence, & evil we see.
And unlike the Deep State conspiracy, it also offers us a
solution, ie, if people want to, they can vote for better
leaders who differ from the same old same old.
I think we're talking about the same processes, but some might be focusing on different aspects.
Where I depart from most conspiracy theories is when they appear too mystical or appear to be "Not Of This World."
I look at it more as a matter of politics being a down-and-dirty fight in the gutter. It's always been that way, even going back to Ancient Rome. Power corrupts, and absolute power corrupts absolutely. Sometimes the bad guys win, and sometimes criminals get away with it. There's nothing mysterious or mystical about it. But I don't see it as all that far-fetched or tinfoil hat stuff. It's a constant within politics as it has been practiced throughout known human history.
As far as actually proving it in a court of law beyond the shadow of a reasonable doubt - that may not be possible. That's another process to go through. After the lawyers get done making their motions and the court decides which evidence is admissible and which is not, then you're stuck with shaky conclusions like "Oswald was the lone assassin" and theories about magic bullets.
