Question Concerning Time

First topic message reminder :

What is the general consensus concerning the approximate time that Lee Oswald was put in handcuffs at the Texas Theater?

I found the anecdote about the accident involving a woman and a police car.

From Joe Mannix.....

"Dallas radio personality Kevin McCarthy had a number of talk shows dealing with the assassination in the late 1980s and early 1990s. Bill Pulte heard this broadcast and repeated the following to me from memory.

A man called into the radio program and told this story. “My girlfriend told me something that might be important about the Tippit murder. She was driving east on 10th Street behind a police car; she was some distance behind it. The officer in the police car hit his brakes quickly and backed the car up very fast. The woman hit her brakes but could not stop completely and bumped the rear of the police car. She said “Oh no” to herself because she hit the police car and thought that the officer was going to be upset and give her a ticket, but the officer did not pay any attention to her. She backed up went around the police car and drove on her way. Later she recalled that the location where this happened was exactly where Tippit’s car was when he was killed, and she realized that she had bumped Tippit’s car.”

Bill Pulte said that “the caller sounded excited and completely unrehearsed, and the call seemed spontaneous” The caller said that his girlfriend refused to come forward with her story because she did not want to get involved."

Could this be the accident involving a police car? Did the woman assume it was Tippit because of the location?

As for Tippit observing "Oswald" walking east while driving slowly on 10th. Pictures I have seen of the street as it was in 1963 show a number of large trees on the same side of the street. I do not think Tippit would have seen anyone walking away until a few seconds due to these trees blocking his view.

There's no discernible damage to Tippit's rear bumper. Her story sounds credible and perhaps the two cars merely bumped. No question that Tippit backed up hurriedly, his rear tires are almost 2 feet closer to the curb than his front tires. 

Was it something he saw in the driveway between 410 and 404 East 10th, that caused him to back up so quickly? So as to block off the driveway? That explanation seems more likely to me, than of "Oswald" walking away and toward the rear of the cruiser. If a suspect walked away I am skeptical that Tippit would act so grandiose & cavalier by hurriedly backing up his cruiser, as if to emphatically state, "Hey! I was talking to you!" I'd guess he would stay put and hop out of his cruiser and perhaps draw a gun. So Tippit's having quickly backed up is a big clue to the crime scene, in my mind.

(this is simply a side view of Tippit's car, with 410 and 404 East 10th in the background, just a few pics down from the 1st at this website)

It is possible that the minor accident was not Tippit's car but the woman assumed it was him. The story related to McBride by Tippit Sr infers it was another officer that was involved. Of course another candidate was Nelson who according to the transcript was called into the Oak Cliff area by Jackson along with Tippit. I don't believe that call from Jackson however Nelson calls in from a point near the Gloco. Strange there are so many candidates for Robertts' patrol car when the WC said there were none.
