Good grief. Again, it's not hindsight. You seem incapable of understanding. I'm not suggesting that Frazier should have known that Oswald was a nut job who was carrying a rifle to assassinate JFK that morning. Can you understand that? What I am suggesting is that AFTER Frazier knew he had driven a nut job who was carrying a rifle to assassinate JFK that all his interests lay in making it appear that he had no cause to be suspicious. So it's difficult to say how much of his testimony was influenced by a desire to downplay the events. This is an obvious point. It requires no hindsight whatsoever. It's all the more rich coming from kooks who have suggested that Frazier and his sister were in on the conspiracy and made up the long bag story to implicate Oswald.
What I am suggesting is that AFTER Frazier knew he had driven a nut job who was carrying a rifle to assassinate JFK that all his interests lay in making it appear that he had no cause to be suspicious.That all depends on when exactly Frazier (and Randle also) learned that Oswald was the main suspect. I seriously doubt that he (they) knew this when he drove back to his sister in Irving and subsequently to the hospital. Frazier left the TSBD, at around 1:30 PM, before Oswald was even arrested! It is entirely possible that he did not find out about Oswald's arrest until after he was arrested at the hospital, which of course means that he couldn't have synchronized his story with his sister.
So it's difficult to say how much of his testimony was influenced by a desire to downplay the events. This is an obvious point. Hardly obvious, as he couldn't have known, in those early hours, that the size of the paper bag Oswald had carried and the implications of that, would be such an issue, until the DPD officers asked him about it. That didn't happen until around midnight, when he was being polygraphed. It was at that time that he rejected the bag found at the TSBD as the bag he had seen Oswald carry.
It requires no hindsight whatsoever. Oh yes it does. And revisionism as well.
