So, only initial statements are of value. I’m sure Chappy will provide his thoughts on that notion.
The initial statements are always the best, but should still be seen as suspect, even in the best of circumstances. This is not the best of circumstances, and not just because it was a delayed memory.
It wouldn’t be so bad if Mrs. Earlene Roberts never had any police cars park outside the house she worked in, where Oswald lived. If that was so, even a delayed memory recall of a police car parked outside the house would be of interest. How could she confuse a memory of a police car parked outside the house on November 22 with a memory from a different date, if there should have never been any police cars parked outside on any day? But that is not the case. There were police cars parked outside the house, on that day, after Oswald was arrested and in the following days. So, it Is quite possible a sudden memory of a police car parked outside around 1:00 pm on Friday was really a memory from a different time, or even from a different day.
A parallel example would be, what if Henry Fonda lived in the area? And he was really keen to investigated himself, as an amateur investigator. So later that day and on other days, he stopped by, sometimes checking out the inside of the house, at other times walking around outside. Then, a week later, Mr. Earlene Roberts, for the first time, claims that Henry Fonda was waiting outside when Oswald stopped by at 1:00 pm. Now, one interpretation would be that Henry Fonda was not acting as a sort of crazy buff but was even more unbelievably part of a conspiracy. But a more reasonable interpretation is that Mrs. Roberts confused one of her memories of Henry Fonda with the events of 1:00 pm on Friday.
As for the clothes.....what a great excuse for a package on Thursday's trip to Irving with Buell. Seems preparation neglected the essentials requiring a risky return to 1026. All that money left at Irving could have been used for a new revolver, jacket and ticket to anywhere by the time Tippit was dead.
But as others have pointed out, Oswald probably never expected to escape Dealey Plaza. He thought people could tell where the shots came form easily. Had he fired from the same level as most witnesses, that would have been the case. But people are not good at telling the directions of an elevated sound. I have noticed that with myself, when people call down to me from a balcony. Where the heck are they?
So, even if successful, there is no need to keep all the money for himself. And maybe he’ll keep a little for himself, in case the motorcade is cancelled or something, so he can buy food and pay his weekly rent until his next paycheck. There is no need for a new revolver because he will be caught within a few minutes of the shooting.
And, yes, he could wash the clothes on Thursday. But he might want to use the time on Thursday evening checking out his rifle, putting it in the bag and hiding it.
I think any plans about buying a bus ticket wouldn’t start to be made until something like ten minutes after the assassination. And that would explain why he didn’t keep enough money to buy a bus ticket, or buy one in advance.
