By no means did 75% of the ear witnesses who reported on the spacing of the shots say the last two shots were 1-2 seconds apart. Most did not put a time on the spacing of the last two shots. Many just described the last two as being noticeably closer together than the first two. Most described a pause after the first shot and then two rapid shots. Several said the last two were about two seconds apart (e.g. Robert Jackson: “I guess, two seconds” ; Roger Craig: “no more than two seconds”). Allan Sweatt thought there were 7 seconds between the first and second and 2-3 seconds after that was the third shot.
Okay, let’s say it could be 2-3 secs. If so then Dans 1st shot Z224, 2nd at Z313 and 3rd at 2-3 secs after that is not so implausible since it’s clear that the 6th floor TSBD shooter was either stupid or was trying to set up Oswald.
1. He chose to shoot at a moving target from 6th floor TSBD. He could have chosen an easier place to shoot at a stationary JFK giving a speech from a much lower elevation thus eliminating changing angles and necessity to constantly be adjusting to track the target. It would have been a much easier one shot one kill.
2. He stuck his rifle out the window for several seconds after firing the 3rd shot. It was spotted by Malcom Couch and Robert Jackson as much as 5 secs after they heard the last shot.
3. He left 3 shells at the window
4. He may have left a paper bag with Oswald’s palm print on it.
5. He moved several boxes up next to the window which had Oswald prints on them.
3. He left an MC rifle linked to Oswald’s P.O.Box on the 6th floor not really hidden so well.
4. He had to either run down 4 flights of stairs or had to use the west freight elevator to go down to the 2nd floor landing. He could not go all the way down to 1st floor because he would have been seen by Adams, Stiles, Lovelady and Shelley ( the 2 men Baker saw) as he exited the elevator
If he took the west elevator down to 2nd floor landing, thus bypassing Mrs Garner on 4th floor unseen, and he exited from the 2nd floor west window onto the garage rooftop to escape then he was a conspirator who had planned to set to Oswald. Thus all the stupid decisions were required to set up Oswald.
If he took the west elevator to the 2nd floor landing thus bypassing Mrs Garner unseen, and he exited and ran into the 2nd floor lunchroom then he was Oswald and the stupid decisions were because Oswald was a stupid Marxist Kook.
In Either scenario, a 3rd shot fired after Z313 is plausible.
