If LHO doesn't get a job at TSBD (or any other location in Dealey Plaza), how would they have been able to frame him?
Even without proof that he was on the Sixth floor when the shots were fired, they were able to say that a rifle that Oswald owned was found in the building where the shots were fired which also happened to be where he worked. That was enough to ensure that he took the Fall for the crime.
Some witnesses placed Oswald on the first floor minutes before the shots were fired but it didn't matter to the Warren Commission of course.
It is helpful to the case against Oswald that he worked in the TSBD as it does place him in the building. And, of course, he was guilty. My point, however, is that it was not NECESSARY for him to be employed in that building to frame him. It's the evidence left at the scene (as outlined by the WC) that links him to the crime. Not simply that he worked in that building. A lot of people worked in the building. Some were, like Oswald, in the building at the time that shots were fired. If, as Martin and some other CTers stupidly suggest, Oswald wasn't even on the 6th floor at the time of the assassination and the fantasy conspirators simply allowed him to roam about, then why couldn't they have framed him from any location? They drop his rifle at the grassy knoll, for example, claim to find his prints on it, and silence anyone who could give Oswald an alibi for the time of the assassination. That's more or less what CTers suggest happened in the TSBD.
It defies belief that any fantasy conspirators would get Oswald a job at the TSBD long before the motorcade route was even planned, and hope based on some precedent that a future motorcade would bring JFK by the building. That is laughable as a plan. And again, how do they ensure that an unstable guy like Oswald even continues to work there or bothers to show up on the 11.22? How do they get him to make an unexpected trip to the Paine home on the night before the assassination? How do they know he is not planning on taking a long weekend with his family? How do they get him to take a long package to work the next morning?
