I think this comes down to a philosophical difference in how we approach truth in the face of uncertainty. The truth here is clearly uncertain (and probably unknowable) at this point. I approach uncertain situations with a Bayesian perspective, meaning I have a certain preconceived understanding of the dynamics at play and I allow facts to shift that conception to ultimately form a conclusion consisting of how likely I believe each scenario.
In this case, history dictates that my Bayesian priors should be strongly shifted towards at least some "conspiracy" at play considering the how other leaders have been killed in the past by some conspiracy. History also dictates specifically that the CIA is capable of similar conspiracies (although this would probably be the biggest/most dramatic). The facts paint a pretty clear picture of how the assassination actually happened, but an entirely unclear picture of the motivations. Other tidbits of information strengthen and weaken these prior understandings (in my opinion they strengthen overall), but since they are only vague tidbits, the shift in understanding is small.
I believe you call this "unsubstantiated" because you do not allow history to form a prior understanding of the dynamics at play. You also seem reticent to allow for fuzzy truths or uncertainties to exist. This is entirely incongruous to the way I, and many other folks on HN, perceive the world, hence the disagreement. There fundamentally is a bottomless pit of possibilities of what happened, but this is the method in which I and many other narrow down that pit to vague likelihoods.
