You tried to make a big deal out of Frazier saying that the bag he had seen was like a bag one gets at a grocery store as if that had some significant meaning to your claim that Oswald had used the heavy duty bag made from TSBD materials to conceal the rifle.You basically implied that a bag from a grocery store was the same as the TSBD bag. Hence the question; Is it your claim that the TSBD was wrapping their books in paper similar to that of grocery store bags?
Aha! You have amended the question from me claiming that the TSBD was wrapping their books in grocery store bags to the more reasonable claim "similar". Now you understand why I scoffed at your question. My answer is that it has the characteristics of a heavy bag one would get from a grocery store and not a thin and crispy bag as had originally been claimed by Frazier. By his own admission, a claim he made that was later amended and then officially discarded.
Stop dodging.You seem unwilling to answer my question. Again, how does 'as best he can' equate with 'completely'?
By the simple fact that NO identifiable prints were found on the rifle on November 22-23, 1963.
If I am not mistaken,there was several rifles found the day of assassination in the TSBD.
