One of the mental blocks people have when thinking about JFK conspiracies is the fact that a great many conspiracy theories are patently absurd. Not just about the JFK assassination, but in general. There is always the risk in this line of thinking of running astray into nonsense. However, for reasons detailed in previous posts, I think there is ample evidence of conspiracy surrounding the JFK assassination, so it’s very different from aliens building the pyramids or similar things. For instance, it’s a fact that the CIA has been involved in overthrowing governments, assassinating people all over the world, and other related operations. We’d be foolish to think to that conspiracies never happen.
In the particular case of the Kennedy assassination, we have to keep in mind that when we study it now we are building on two generations’ worth of research. At the time of the assassination many different witnesses saw, heard, and did many different things, but there was no way at the time for them to all form a narrative together. This had to be constructed slowly, piece by piece, over many years. It would have been too obvious at the time if all this were known—but it was not even knowable at the time.
Whoever the conspirators were, they were operating in the assumptions of their time. Nobody could have predicted the ways in which conditions would change. The conspirators—before and after the fact—had no way of knowing that one day there would be this thing called the internet by which people could assemble a bird’s eye view of the entire sequence of events. They had no way of knowing that Jim Garrison would launch an inquiry into the plot and bring it into public focus. They had no way of knowing that there would ever be a House Select Committee on Assassinations which would release a lot of secret government information about the assassination, autopsy, and investigation to the public. Even the old-fashioned ways of disseminating information available at the time (books, newspapers, magazines, and film) relied on information that was hard to come by. The Zapruder film wasn’t seen by mass audiences until 1975. The government clearly took as many precautions as it could get away with at the time to prevent people from talking. The shooters likewise had methods of keeping things secret; even after all this time, it’s still not conclusively known who they were. If these two groups were related, well, all the more reason to take whatever precautions they could.
On top of it all, there are many people are are faithful enough to the system and who lack creativity enough to ever question the official version. There are people and institutions whose very mission is to scoff at those who question official versions of anything. Even after all that’s been published on the subject, even after the HSCA’s investigation, you’d be hard pressed to find a serious treatment of the evidence for conspiracy in the JFK assassination in a major media outlet.
Many people hear some of the evidence and think it’s not possible that all this information could have been around right after the assassination without alerting the public to a conspiracy. All this information existed somewhere, but none of it existed everywhere.
