"How is leaving money for one's wife evidence of murder?"
>>>On its own? Where did anyone say that?
Again, he characterizes Oswald leaving nearly all of his money - $1200 in today's dollars - as simply a husband leaving his wife money. And he did so the day of the assassination and not, as Marina said he usually did, on Monday. He was, she said, going to see her that weekend. So, why not leave it on the Monday? Per the usual routine?
And then he isolates this act out of the other evidence of Oswald's behavior and activity. And says how does this - and this alone - prove anything. Even though no one said this and this alone proves he shot JFK.
We are trying to reason with someone who looks at the evidence this way.
It can't be done.
