The greatest asset of a conspiracy theory, is that no facts or evidence is necessary. One merely chooses the conclusion one desires, then collect snippets of information to confirm one's conclusion, easy peezy. One then rejects any and all evidence that is contrary to one's conclusion, classing such information as "f**e news".
A conspiracy theory never needs fool proof, iron clad evidence to back it up, because the conclusions were drawn BEFORE the collection of evidence or research details. Many innocent persons have been jailed, because law enforcement determined who was guilty BEFORE beginning an investigation into a crime, then collected only that evidenced that supported their conclusion.
A case in point; the investigation into the B******i disaster was conducted at least three times, the conclusions of the first two hearings were rejected - because it's conclusions did not match the desired outcome ( the first two absolved Secretary Clinton of malfeasance ). The third and final hearings ended..............when unrelated but damaging evidence was found, i.e. "e-mail gate". Do you see? The hearings were conducted to find the t***h of the matter, but the t***h was rejected, with further "hearings" conducted over months and months ( costing taxpayers many millions of $ ), until the conspiracy theory could be supported. In this particular case, the original theory ( Clinton knowingly delayed help for the Embassy ) was dropped - because a much more damaging circumstance was found accidentally.
Drawing conclusions in advance of investigation, defies common sense or the scientific process, but is enormously popular. No matter how outlandish a conspiracy claim, it will find people willing to believe it and support it with their own "evidence". In many, many cases, the LACK of evidence one way or the other is used as proof of the claim, because it can't be refuted ( missing e-mails or texts is PROOF of nefarious activity, etc.).
Wh**ever you are is willing to believe, usually as a result of fear or anger, you'll will find many other people supplying you with fodder for your fear and anger, along with the "proof" of their claims...............proving that you were right all along. Conspiracy theories are wonderful, because you can never convince their adherents that they are wrong.
