Nobody will ever put all of the conspiracy theories to rest.
Even if the official version from the “Warren Report” is the truth, there was so much evidence that was lost, destroyed, or ignored to ever know the truth.
Oswald’s rifle still exists, and I bet the paper wrapper does to, since it was recovered from the TSBD. Very easy to take the rifle apart and see if it matches the fold lines in the paper. I bet it’s been done several times.
Just very odd, that on that day of days, Oswald decided to bring “curtain rods” to work (Oswald’s own story).
