You always answer fact with theory. Two witnesses said the killer touched the door, and one of them said the killer spoke with Tippit through the window below which the prints were found.
Who were these three witnesses? You keep referring to them but never name them and quote what they said. Please do so. And which one(s) said he also touched the fender?
The car window was closed. The killer had to talk through the little window vent on the side. And Markham testified that he puts his *arms* on the ledge not his hands. Although she incorrectly said the window was open.
WC testimony:
Mrs. MARKHAM. I saw the man come over to the car very slow, leaned and put his arms just like this, he leaned over in this window and looked in this window.
Mr. BALL. He put his arms on the window ledge?
Mrs. MARKHAM. The window was down.
Mr. BALL. It was?
Mrs. MARKHAM. Yes, sir.
Mr. BALL. Put his arms on the window ledge?
Mrs. MARKHAM. On the ledge of the window.
