Again, Oswald himself denied carrying any long package. So unless you begin with the premise that Oswald lied it doesn't really matter what Frazier said. To cling to Frazier's estimate as being absolutely precise entails needing to explain why Oswald denied carrying any such package. If it didn't contain the rifle because it was too short per Frazier, then why does Oswald lie about it? This where the kooks stick their head in the sand and make claims like there is no recording of the Oswald's interrogation. The old impossible standard of proof trick where any evidence they can't rebut is rejected as the product of lies or fakery - but without any evidence of such. The great circle of lunacy that allows them to make an allegation, not support it with any logical explanation, and then wave away evidence to the contrary as a product of the frame up.
