So, it's just another one of your unsubstantiated assumptions. Got it.
Perhaps you have trouble understanding " Let's take item number 1".... IOW Let's take it one baby step at a time , so that you can keep up.
On the original sheet for 11-22-63 what does it say about item # 1 ?
" Found by Dept. Sheriff Weitzman on the sixth floor, 411 Elm, 5' from west wall and 8' from stairway." This tells us that Seymour Weitzman discovered a 6.5 Italian make rifle, and NOT A 7.65 MAUSER. The rifle was EIGHT FEET from the stairs.....or IOW the model 91/38 6.5mm Mannlicher carcano was about 5 feet south of the row of boxes that formed the south wall of the east/ west aisle at the top of the stairs. It was NOT jammed between boxes of books about three feet from the stairs.
Do you understand this elementary information?
