You mean that there is no "direct" evidence that puts C2766 in Oswald's hands. There is plenty of evidence. More than enough for a jury of reasonable people to conclude beyond a reasonable doubt that Oswald fired three shots at the President's limousine with it.
Not without a massive amount of assumptions that a reasonable person would never make.
There is plenty of evidence.What evidence would that be?
Can you show that;
- the MC rifle found at the TSBD was ever stored in Ruth Paine's garage?
- Oswald made the paper bag found at the TSBD and took it with him to Irving on Thursday evening?
- the paper bag Frazier and Randle saw Oswald carry on Friday morning contained the MC rifle?
- Oswald was on the 6th floor of the TSBD at 12.30 PM when the shots were fired?
- Oswald came down the stairs unnoticed within 75 to 90 seconds after the last shot?
The answer to all these questions is a simple one; No you can't.
