As a high school student I traveled to Dallas in '64. I went to the location. The thing that struck me the most was how any average shot could have hit JFK from the other window with a pistol as the limo virtually stopped to make the turn.
The only reason to wait is that Oswald was not expected to make the kill shot. I believe the shot was made by a marksman in the building beside the book depository in the corner of the turn. It is all so closed in.
The much easier shot was when the limo was on Houston St.
We visited the School Book Depository museum when it first opened. At that time, they allowed visitors to stand at the correct window. The window that is now open and is posted online isn’t the correct one so messes with the angle. In our opinion, with the downward and curving left on Elm is too hard a shot from the correct window.
The question I want answered is Officer Tippet’s wacky movements. His house was at the end of our street and Oswald’s was around the corner of our doctor’s office so I knew the neighborhood. Why was he not within his partol area? Why did he suddenly rush into the record store to make a call? Why did he head pretty much straight to where Oswald was walking? He knew of Oswald as they ate at the same cafe but just how well did they know each other?
There was a show on the History Channel that claims Oswald was headed to an Iraqi safe house when he ran into Tippet. That seems plausible.
Oswald qualified with open sights over 200 yards. Next, there is a picture of the second building and no person with a rifle there.
