The mechanics are or were indeed simple - as JFK said, if someone wanted to shoot him from a tall building with a rifle and didn't care about being caught there's nothing that can be done about it - but Oswald clearly got lucky.
It's been more than half a century. If there was a larger conspiracy behind the act the evidence for it for me would have been found somewhere at some time. But it hasn't. This has been the most studied event in US history.
If someone came forward today claiming to have been part of a conspiracy to kill JFK would you believe the person? Probably not.
At this point, people are pretty Dug into their own theories about what happened. Plus the various law enforcement agencies involved would never admit that they lied or were wrong in their conclusions.
We've had multiple government investigations, multiple investigations by the news media along with 50+ years of investigations/books/studies by various authors, e.g,. Caro, Weiner et al. into the major figures at that time, e.g., LBJ, Hoover, et cetera. And all of that shows nothing. The conspiracy crowd likes to harp on the failures of the WC and ignore all of these other investigations.
The various law enforcement agencies were never completely cooperative and there?s lots of holes in the evidence. Even the CIA no longer denies that there was a Cover-up. We can?t possibly know the whole truth given those circumstances.
Look at the evidence pointing towards Oswald. And the lack of evidence pointing elsewhere. One can only reasonably conclude that Oswald alone killed JFK. In order to argue otherwise one has to engage in some fanciful thinking.
The evidence doesn?t conclusively prove that:
- Only three shots were fired
- all shots were fired from the weapon found in the Book Depository
- Oswald had a motive
- Oswald had no accomplices
It?s fine if you?re satisfied with the evidence that we have but don?t criticize others who are rightfully skeptics about the situation
