No they really have not
Like many people i started out believing the conspiracy theories.
After decades of reading books and watching documentaries about them I read the other side of the story ( which you have not ).
The conspiracy theories have all been disproven. Not challenged or refuted or debunked but disproven
Good for you. Disagreeing with you doesn’t make anyone else (or you) the “dumb” one.
But let’s settle down a bit and consider some points.
One piece of physical evidence which would make the headshot being fired from in front or from behind, is the piece of skull recovered the next day by some pre-Med student.
It was photographed and forensically analyzed. The analysis advised
The Warren Commission concluded that the fatal wound of entry was
slightly above the
occipital protuberance.
Yet, they used a drawing to show the wound of entry, instead, going through the upper
parietal part of the President’s skull.
Why it matters:
There was allegedly some “beveling” of the interior portion of the “occipital” bone recovered the next day. If so, and assuming the bone came from the president’s skull, such beveling would establish the shot from behind. However, it was later discerned to be a PARIETAL bone fragment. This raises a concern that the bone fragment, allegedly recovered the next day, might not be from the President at all.
If it had been preserved, it could be subjected to DNA analysis. (At least Mitochondrial DNA.)
But the skull bone fragment went missing.
There are many other reasons to reject the WC conclusions. I’ll leave you with one: I had earlier suggested that the fatal head wound-of-entry was at the President’s hairline above his right eye.
What if an autopsy photo showed that wound? It might just be a clue as to whether it was, itself, relatively small suggesting a wound of entry shot from in
front of President Kennedy?
