I don't know why people are so obsessed with this conspiracy theory. Occam's Razor says it was Oswald. Why invest time speculating and arguing over it when there is no way to verify anything? This new revelation doesn't change anything, it's just hearsay.
It's amazing that people in 2023 can be just as accepting of the mainstream narrative as the average joes in the 60s, that were subjected to a top down narrative decided by the powers that be using 3 TV channels and 2 newspapers.
