Not sure what questions I missed? If I missed responding just send me a reminder and I will respond.
First of all, the trajectory has everything to do with CE399. The path through JFK's neck into JBC's thigh, butt-first, explains the condition of CE399 (as well as the first shot hitting JFK and the second hitting only JBC, the 1.......2...3 shot pattern, Tague's evidence, Greer, Hickey, Powers, Gayle Newman etc).
As far as the evidence that the shots came from the SN there are several witnesses whose evidence puts the shots originating there: Robert Jackson, Mrs. Cabell, and Amos Euins saw the rifle in the window during or immediately after the shots. Arnold Rowland saw a man with a rifle 15 minutes before the shots. The three men below on the 5th floor heard 3 loud shots from above them and Harold Norman heard the bolt action operated 3 times and heard 3 shells hit the floor.
Furthermore, the rifle found on the 6th floor had fired CE399. There were boxes in the SN placed in an unusual way consistent with use to support a rifle. Most witnesses said the shots all sounded similar and almost all witnesses said the shots sounded like they all came from the same location (although there was disagreement as to the location of the source).
If that's not enough, let me know and I will refer to more.
There are so many assumptions here that I don't even know where to start. Oh well, let's give it a try.
First of all, the trajectory has everything to do with CE399. The path through JFK's neck into JBC's thigh, butt-first, explains the condition of CE399And you somehow know it was CE399 that passed through JFK and JBC? How exactly did you reach that conclusion?
Robert Jackson, Mrs. Cabell, and Amos Euins saw the rifle in the window during or immediately after the shots. Arnold Rowland saw a man with a rifle 15 minutes before the shots. They saw which rifle? Since when does seeing a rifle equate to seeing a rifle being fired?
The three men below on the 5th floor heard 3 loud shots from above them and Harold Norman heard the bolt action operated 3 times and heard 3 shells hit the floor. How does what they think they heard prove that a rifle was actually being fired on the 6th floor?
the rifle found on the 6th floor had fired CE399.
When exactly was CE399 fired by that rifle and how do you know?
So, now it's my turn.
What evidence is there that the bullet now in evidence as CE399 was ever at Parkland hospital in Dallas?
The chain of evidence for that bullet starts at the FBI lab in Washington!
None of the four men who were involved in the discovery and transportation (to DC) were able to positively identify CE399 as the bullet they had seen on 11/22/63
In mid 1964 the WC asked the FBI to authenticate several pieces of evidence, including CE399.
Although the FBI later claimed in CE2011 that Tomlinson and Wright thought that it was the same bullet, this so-called "identification" conflicted completely with the content of an Airtel message from SAC Shanklin in Dallas, which clearly states that both men could not identify the bullet. In addition they claimed in CE2011 that SA Odum had shown the bullet to Tomlinson and Wright, but Odum is on record saying he never did such a thing and that he never had CE399 in his possession. Add to this that Wright later stated that the bullet he had seen was pointed which CE399 clearly isn't you you've got all sorts of evidentiary problems you just can't ignore.
