That doesn't make sense. Apples & oranges.
There is evidence for both arguments, re: Whaley and whether Oswald was/was not wearing a jacket in the cab.
Unless of course you can cite for Earlene Roberts saying anything which is at odds with her statements that Oswald left in a jacket. Betcha can't.
You're such a hypocrite.
You can't cite any statement by Frazier that is at odds with the way he described Oswald carried the package (in the cup of his hand and under his armpit) yet you don't believe him.
Why, because he is saying you don't like.
Roberts on the other hand is saying something you not only do like but desperately need to keep the narrative alive. That's why you blindly believe her.
Roberts couldn't even identify the jacket when it was shown to her during her WC testimony and she went completely of the rails by claiming the jacket she had seen was dark colored
