Did not Oswald supposedly make the bag out of TSBD paper and tape from the dispenser roll by that station on the ground floor of TSBD?
That would be Thursday morning so that’s him planning something well BEFORE he had yet found out that Marina wanted a divorce.
For all Oswald knew, he was going home a day earlier this week because he hadn’t been able to see Marina the previous weekend because Ruth Paine was throwing a party and he had been told not to come.
So wouldn’t Oswald be optimistic? A guy looking forward to seeing his wife and kids , for a long 3 day weekend yet he is also planning a murder?
He must have really wanted to move up from his mule job in the mafia to being a made man?
