I was talking about the need to discard some things relating to the case (e.g., witness testimony that is obviously inaccurate), not necessarily physical evidence. Since there is no "non-Oswald" physical evidence, then there is none of that material to discard -- although most CTers have decided to discard all of it by way of calling all of it fake. But, then too, that's the only way they can pretend Oswald was a patsy. So they're pretty much forced to toss all the evidence in the dumpster.
You're not making sense, David.
There is no physical evidence for or against Oswald. There is only physical evidence that is being interpreted for or against Oswald. Take for instance the order coupon for the rifle. In one interpretation it could be against Oswald, because his P.O. Box was used and he potentially wrote the form. On the other hand it could be interpreted for Oswald, because it was A. Hidell who ordered the rifle and not Oswald.
Now let's get back to the paper bag found at the TSBD.
We have two witnesses who both say that the bag found at the TSBD is not the bag they saw Oswald carry. Frazier told the investigators, the bag fitted between the cup of Oswald's hand and his armpit and he also showed FBI agents to where the bag reached on the backseat of his car and the FBI agents measured the distance as being 27''.
Linnie Mae Randle told FBI against Odum and McNeely she saw Oswald holding a bag at the (folded up) top and carry it next to his leg. If that bag contained a wooden stock of a rifle it would have had to have been at least 34" long, which means it would have hit the ground, as Oswald's legs, measured from his hip, were not not 34" long. As the package didn't hit the ground it is reasonable to assume that the bag was shorter than 34". In fact, the bag that Oswald could have carried in the way Linnie Mae Randle described could not have been much larger than 27".
So, estimates aside, we have two measurements of the package compared to (1) the backseat of Frazier's car and (2) the size of Oswald's leg and a visual comparison of the size of the package in relation to the length of Oswald's arm. That seems pretty definitive to me. But that's not all. On Friday evening, only hours after the event and while he was being polygraphed, Frazier was shown the bag found at the TSBD and he rejected it as the bag he had seen Oswald carry. He described the latter as being "a thin, flimsy sack like the one purchased at a dime store".
As far as the bag is concerned that's the evidence interpretation for Oswald. Now, what exactly is there against Oswald?
The bag was (allegedly) found in the sniper's nest. It turned out to be made of materials that are common to the TSBD. Several prints are on the bag, but the only ones that could be identified belong to Oswald, which is somewhat remarkable as we know that at least Detective Montgomery handled the bag also (he unfolded it and carried it out of the building). It was never established that the bag found at the TSBD ever left the building, nor that it ever contained a rifle. So what we are left with is a bag, made from TSBD material, found inside the TSBD with prints of an employee of the TSBD on it.
Now, can you tell me, what plausible reason (other than circular logic) the investigators had to ignore the witness evidence as "mistaken" in favor of the TSBD bag being the one that Oswald carried after all?
