The point I was leading up to (but ignored by the thread's creator) is that just because Jimmy Burt said the killer put his hands on the door doesn't mean it's a fact that the killer indeed placed his hands on the door.
Jimmy Burt also stated that when Tippit pulled up alongside the guy, he (Tippit) leaned over and rolled down the window. The window was NOT rolled down. Burt made an assumption about the window and therefore could have made an assumption about the killer touching the door.
Helen Markham also said the man touched the door. In addition, she, too, said the window was rolled down. I quote from her WC testimony.

Mr. BALL. The police car stopped?
Mrs. MARKHAM. Yes, sir.
Mr. BALL. What about the man? Was he still walking?
Mrs. MARKHAM. The man stopped.
Mr. BALL. Then what did you see the man do?
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.
Mr. BALL. And the policeman was sitting where?
Mrs. MARKHAM. On the driver's side.
Mr. BALL. He was sitting behind the wheel?
Mrs. MARKHAM. Yes, sir.
Mr. BALL. Was he alone in the car?
Mrs. MARKHAM. Yes.
Mr. BALL. Then what happened?
Mrs. MARKHAM. Well, I didn't think nothing about it; you know, the police are nice and friendly, and I thought friendly conversation. Well, I looked, and there were cars coming, so I had to wait. Well, in a few minutes this man made--
Mr. BALL. What did you see the policeman do?
Mrs. MARKHAM. See the policeman? Well, this man, like I told you, put his arms up, leaned over, he just a minute, and he drew back and he stepped back about two steps. Mr. Tippit--
Mr. BALL. The policeman?
Mrs. MARKHAM. The policeman calmly opened the car door, very slowly, wasn't angry or nothing, he calmly crawled out of this car, and I still just thought a friendly conversation, maybe disturbance in the house, I did not know; well, just as the policeman got. . . .

One of the officers may have rolled up the window before the car was photographed.
We both know that if those fingerprints had turned out to be Oswald's, you would not be reaching and straining to deny that the killer touched the door.
