But what difference does it really make which door Oswald utilized to leave the building? Whether it be the back door or the front door, there is no doubt whatsoever that Lee Oswald WAS inside the building at circa 12:32 PM and he then got onto a bus (and then a cab) a few minutes later. You surely don't deny the fact that Oswald made it to his roominghouse by about 1:00 PM, do you? Therefore, Oswald definitely DID leave the TSBD building within a very few minutes of the shooting. That fact is beyond all doubt (even amongst CTers).
Also....
When I discussed Oswald's "unusual" actions on 11/21 and 11/22, you need to ADD UP ALL of those actions and movements, instead of isolating just one of them (which is what you did above).
And when ALL of those actions/movements are added together, the result is, IMO, a person named Oswald who certainly was NOT an innocent "patsy" on 11/22/63.
Dave, as you well know they think, insist really, that Oswald was framed for the assassination of JFK. And then further framed for the murder of Tippit. And then sort of post-framed for the attempt on Walker (Oswald is dead; why would they need to frame him again? and risk revealing the conspiracy? for what purpose?). And along the way all of these separate lines of evidence in each case, in the assassination, in the shooting of Tippit, in the attempt on Walker, was faked, manufactured, falsified. All of it. Every single piece. The physical, the eyewitness and the circumstantial. Meanwhile, all of Oswald's behavior is innocently explained away and all of the behavior of others implicating him is considered corrupt, e.g., they lied or were ordered to lie or were coached.
Then the multiple investigations into this, by several generations of Americans of various backgrounds over decades both in the government and in the media, covered up what happened. So it was done, then covered up at that time, and then the cover up has itself been covered up over the following decades. By a different group of Americans - Democrats and Republicans can't agree on a single thing; but they agreed on this? Really?. And why? The media, the same one that exposed the crimes of the government have also covered this up. Because Operation Mockingbird or something (so the same media that exposed these other abuses were ordered by the CIA to coverup for the assassination and they did so?).
This is, frankly, a psychosis, a detachment from reality. It is not possible to do this. The government is a bureaucracy; it's not a monolithic "thing." We know it cannot be done; they think it not only is possible but was done. There is no way to persuade a person with this view that they are wrong. Whatever evidence you present will simply be added to their mountain of conspiracy. It's why when a new "discovery" from the files are found it's simply added to their conspiracy view. If we found 10 more witnesses that he shot Tippit or was seen fleeing then would simply add that 10 to their conspiracy. Another 10 were coached or ordered to identify him.
We can try but, again, as you know it's not going to work. The only way they can get out of this view, this detachment from reality, is by themselves, their own re-discovery, their own realization. Otherwise they simply consider what we say as more lies by fools or by disinformation agents.
