Since CE-142 is the bag that carried CE-139
When you say it like that, you really, really, need to back up that wacky claim by some hard evidence.
Since Oswald carried no lunch bag that morning BWF could not have seen any bag other than CE-142. It is really quite simple,
Simple or not, Frazier has denied all his life and from day 1 that CE-142 is the bag he saw Oswald carry.
But let me guess, he, who actually was there and saw the bag, was wrong and you, who wasn't there and never saw the bag, are right, correct?
The evidence has been around for public consumption for over 54 years and all that needs to be done is to read the WR, which is my source (along with the accompanying 26 volumes of hearings and exhibits). BWF has also maintained that he wasn't paying too much attention so his recollection as to the size of the bag can't be expected to be anywhere close to an exact measurement of the bag.
