Quote:(3) Oswald told Frazier he would NOT be coming back to Irving on Friday night.

First point... this is hearsay. It's also interesting to note that Frazier was very nearly arrested for the murder of JFK... his rifle was confiscated, and he was subjected to a forced lie detector test. 
 
As well, Why would this be strange??? When Oswald got a ride with Frazier to go to Irving on a Thursday, it didn't mean that he was required then to also come back on Friday and stay the weekend.
 

What Bugliosi is doing here is starting with the presumption that Oswald is guilty,
then defining everything he did and said as evidence of the guilt he's already started with.

Bugliosi knows very well that Oswald, while frequently visiting Marina on the weekends, did not ALWAYS visit on the weekends. (And he lied on that point...)

Interestingly, it seems that Oswald had intended to visit on the weekend, just not Friday night... from Marina's testimony:

Mr. RANKIN. When he said he would not be home that Friday evening, did you ask him why?
Mrs. OSWALD. Yes.
Mr. RANKIN. What did he say?
Mrs. OSWALD. He said that since he was home on Thursday, that it wouldn't make any sense to come again on Friday, that he would come for the weekend. 

"that he would come for the weekend." - this one little snippet belies the notion that Oswald had some sort of nefarious plan that would prevent him from visiting Marina – HE WAS PLANNING ON DOING SO.

This is a common theme among Warren Commission Believers – presuming Oswald's guilt, then going back and looking at everything he did or was presumed to have done in light of that guilt – portraying all actions as 'proving' the presumed guilt. But nothing Oswald did or said is contrary to his innocence, although no Believer would admit this fact.

Attempting to use hearsay of a man's future actions that have nothing whatsoever to do with murdering someone to 'prove' that he murdered the President is just another example of this reoccurring theme of presuming first the guilt, then examining all actions and statements to "prove" that guilt.
