A lot of made up assumptions by nutters, excuses really, throughout this thread are not reflected in the WC conclusions.
And your point is? There is nothing epistemologically suspect about assumptions. All of science is based on the assumption that the universe operates according to principles that will be the same tomorrow as they are today and were 100,000 years ago. I operate on the assumptions that the sun will rise in the morning, my wife will not have left me, and my car will still be in my garage. If you think the assumptions in this thread are "made up" or otherwise flawed, point out the flaws. If you think the inferences in this thread are unreasonable, point out why they are unreasonable and what you believe more reasonable inferences would be.
The fact is, the evidence pretty well screams that Oswald got his rifle from the garage, carried it into the TSBD and shot JFK. The WC did not have to go through the level of analysis we are attempting here, although they did have to account for Frazier's and Randle's testimony regarding the length of the package and the way Oswald carried it. "No, he was really carrying curtain rods" and "No, he was really carrying his lunch" are simply not plausible theories - they simply don't fit the evidence and most reasonable inferences from it. This is precisely why I challenged CTers to present a rational, coherent, evidence-based explanation for either curtain rods or a lunch. Go for it, if you can.
Yes, I assume Ruth and Marina were not lying. I assume neither Frazier nor Randle was a participant in an assassination conspiracy. I assume Frazier and Randle did not invent the curtain rod story. I assume the rifle was still in the Paine garage on 11-21. Those are probably the only real assumptions. The rest of the scenario is either evidence-based or based on reasonable inferences that flow from the evidence. Based on the totality of assumptions, evidence and reasonable inferences, I conclude that Frazier and Randle were either mistaken about the length of the package or intentionally invented a shorter package because Frazier was a suspect and owned an even longer rifle.
If you can do better, show us. Be sure to recognize the critical distinction between "reasonable assumptions and inferences" on the one hand and "raw ad hoc speculation" on the other.
