After all this time here do you actually still believe that Oswald committed anything?
I don't have any theories as the information is too garbled to make sense of it. I think a new investigation should be established to put all these questions to bed once and for all. There is reason to as there is now more information available in the released ARRB documents.
I doubt anyone has meaningfully read all the 2 million documents released. A new investigation should be tasked with actually reading what was released.
