Frazier, how?
Frazier has repeatedly said over the years, without deviation, that Oswald told him that the paper bag LHO took into the TSBD contained curtain rods. And we know that was a lie.
How do I know it was a lie?
Because if LHO really did carry curtain rods into the Depository Building on 11/22/63,
Oswald would have told the police that fact after he was arrested, and Oswald would have certainly produced the curtain rods as well. But he said nothing of the kind. Instead, Oswald told Captain Fritz that he had never said a word to Frazier about any curtain rods and had only carried his lunch into the building on 11/22.
Reasonable inference = Oswald lied (twice). He lied to Buell Frazier when he told Frazier the bag contained curtain rods. And he lied to the police when he said that he (LHO) had never said anything about curtain rods to Frazier.
Otto Beck knows all this, of course. But he has to play his little CT games. I've played this same game with dozens of other CTers in the past.
Next up from Otto? Probably the old standard of:
You've only got Frazier's word about the curtain rods. Why should I believe him?
