I have "blind faith" when the person who was present at the event with no apparent reason to lie about an innocuous event (i.e. he asked Oswald whether he carried his lunch that day and Oswald said no) confirms this happened. How exactly could this be proven to your subjective satisfaction absent a time machine? The real knee slapper is that you are relying on this same witness - who you appear to be suggesting lied about asking if Oswald had his lunch - for his estimate of the length of a bag that he hardly saw. Riddle me this Batman, if Frazier was willing to lie about Oswald not carrying his lunch - again as you suggest he did - then why wouldn't he also confirm the more important fact that the bag was long enough to carry the rifle? HA HA HA. I know logic and common sense are not among your strong points but this is actually embarrassing.

Sure, but your blind faith disappears like melting snow when that same person, who was present, says that the bag found at the TSBD wasn't the one he saw Oswald carry! Go figure...
Frazier saw Oswald carry the package underneath his armpit and in the cup of his hand. That's not an estimate. All you need to do is find out how long Oswald's arm was.
