Back to the sack-----
From the Warren Report.....
Fibers in paper bag matched fibers in blanket.--When Paul M. Stombaugh of the FBI Laboratory examined the paper bag, he found, on the inside, a single brown delustered viscose fiber and several light green cotton fibers.198 The blanket in which the rifle was stored was composed of brown and green cotton, viscose and woolen fibers.199
The single brown viscose fiber found in the bag matched some of the brown viscose fibers from the blanket in all observable characteristics.200 The green cotton fibers found in the paper bag matched some of the green cotton fibers in the blanket "in all observable microscopic characteristics." 201 Despite these matches, however, Stombaugh was unable to render on opinion that the fibers which he found in the bag had probably come from the blanket, because other types of fibers present in the blanket were not found in the bag. He concluded: All I would say here is that it is possible that these fibers could have come from this blanket., because this blanket is composed of brown and green woolen fibers, brown and green delustered viscose fibers, and brown and green cotton fibers... We found no brown cotton fibers, no green viscose fibers, and no woolen fibers.
So if I found all of these then I would have been able to say these fibers probably had come from this blanket. But since I found so few, then I would say the possibility exists, these fibers could have come from this blanket.202 Stombaugh confirmed that the rifle could have picked up fibers from the blanket and transferred them to the paper bag.203 In light of the other evidence linking Lee Harvey Oswald, the blanket, and the rifle to the paper bag found on the sixth floor, the Commission considered Stombaugh's testimony of probative value in deciding whether Oswald carried the rifle into the building in the paper bag.
Coulda..woulda..shoulda...possibly.. maybe.. is not positive evidence.
Gee--- if we only had someone who saw Oswald conspicuously
coming into the building carrying a large HEAVY paper package
