Huh???

Because Oswald lived in Dallas, a likely campaign stop for JFK in the upcoming election. Because JFK's trip to Dallas was announced on September 13, nine weeks in advance of the trip.

And why in the world would the Cubans have assumed that Oswald could only do the shooting if JFK rode by his workplace?

Of course, you are assuming a priori that Oswald was the gunman and that the Cubans would have recruited him to be the gunman, whereas the Odio evidence shows that anti-Castro Cubans were trying to frame Oswald for the assassination weeks in advance of the shooting.

Also, the released HSCA Lopez-Hardway report shows that someone was impersonating Oswald in Mexico City to try to further paint him as a pro-Soviet, pro-Castro Marxist.

I think you're forgetting some of Russo's arguments. For example, he presents evidence that suggests Oswald was supposed to get a ride to Cuba from Red Bird Airport in Dallas after the assassination, and that pro-Castro Cuban Quinton Machado cut a deal with Oswald to bring him to Cuba after the shooting (Live By the Sword, pp. 308-309). 

In any case, even if Oswald had done the shooting after "only" being encouraged to do so by pro-Castro Cubans, this would still constitute a conspiracy; this would still mean he was not a "loner"; and this would make the Cubans who urged him to do the shooting "accessories before the fact"--and they would have risked being arrested, charged, and prosecuted for murder in the second degree.

I'm not going down the path of a religion debate, nor am I really pooh-poohing your beliefs. If they work for you, that's fine. My wife is actually much more conventionally devout than I am, and we get along fine AS LONG AS SHE JUST LISTENS AND SHUTS THE HELL UP!!!  My conversion to Christianity some 56 years ago was via a startling and wholly unexpected experience that could easily be fodder for my "Weird Tales" thread. I have spent the subsequent 56 years far deeper into theological, scientific and psychical studies than JFKA studies, which are really little more than a blip on my radar screen. I know the evidence that is out there in a way that someone who hasn't done the homework couldn't possibly know, and there is no way I could summarize it on a forum like this. Suffice it to say, I believe - and you are free to disagree - that what I call "Christianity, Inc." is nothing more than a profit-driven industry and has little or nothing to do with what Jesus was actually talking about. One real eye-opener for anyone who has never done it is to intensively study the history of the first 200 years of Christianity - it's a weird and wild picture that bears scant resemblance to the Christianity, Inc. of today. I understand that not everyone has the time or inclination to examine and question orthodox dogma, and that's fine - but this wasn't a route I could accept, which is why I lasted precisely one year at Golden Gate Baptist Theological Seminary before saying "Nope, not gonna pretend anymore."

How do you explain JBC hearing a shot and turning to look over his right shoulder, as we see him do starting at Z164, and then about 3 seconds later get hit by the single bullet if he did not hear an earlier missed shot.

We have all viewed the images of the "bucket" sitting on the ground alongside the JFK Limo at Parkland Hospital. And we have been told that the bucket came out of the JFK Limo trunk. That this out-of-place bucket held the tool(s) and nuts-n-bolts that were required to install the JFK Limo Top. This "tale" is simply another JFK Assassination Urban Legend. It's been repeated over-n-over until it has been accepted as being fact. It is Not Fact. It is Fiction. That Bucket did Not come out of the trunk of the JFK Limo. It did Not hold tool(s) or nuts-n-bolts. That bucket came out of Parkland Hospital. It is a "Scrub Bucket". It was used to "Scrub Down" the backseat area of the JFK Limo. This "Scrub Down" made the backseat area of the JFK Limo an ALTERED CRIME SCENE. ALL FBI Photos of the JFK Limo backseat area are photos of an Altered Crime Scene.
If this bucket originally came out of the JFK Limo Trunk, it should have gone back into the JFK Limo Trunk after the JFK Limo Top was installed. This "Scrub Bucket" did NOT go back into the JFK Limo Trunk after that Top was completely installed.
I have found B/W film footage showing the JFK Limo Top having been completely installed, and the JFK Limo Trunk CLOSED. All work on the Top is done. This film footage also shows a suited man walking alongside the JFK Limo. He is carrying the "Scrub Bucket" by its' handle toward/into Parkland Hospital. He is walking AWAY from the JFK Limo Trunk with this "Scrub Bucket" in hand. This "Scrub Bucket" originated from Parkland Hospital, and this suited man is now returning it to whence it came.
