You are talking about very specific forensic evidence. As I used to suggest to Sandy Larsen, take your theory to the Journal of Forensic Sciences, https://www.aafs.org/journal-forensic-sciences, and see if it survives the peer-review process. It won't, but at least then you can write an article for Jim DiEugenio as to how even the Journal is in lockstep with the LN narrative.
We both know you guys would just ignore it, just like you did when the
Journal of Forensic Sciences published Don Olson and Ralph Turner's detailed article on the photographic evidence that JFK was hit just before Z190:
Don Olson and Ralph Turner, “Photographic Evidence and the Assassination of President John F. Kennedy,”
Journal of Forensic Sciences, 16:4, October 1971, pp. 399-419
Even when the HSCA's photographic evidence panel confirmed that the Zapruder film and the Willis slides prove JFK was hit at or before Z190, you guys still refused to face facts on this issue because Connally was clearly not hit until Z234 at the earliest.
You don't have to be a forensic expert to figure out that if there was no hole through the tie, then no bullet exited the throat nor exited the shirt slits because the tie knot was neatly centered between JFK's collar and was directly over the shirt slits. This, of course, explains why no metallic traces were found around the shirt slits, and it explains the fact that Dr. Carrico and one of the Parkland nurses confirmed that the nurses made the shirt slits when they were hurriedly cutting away JFK's clothing. It also explains why two other Parkland doctors said the throat wound was visible before JFK's shirt and tie were removed--no wound at the level of the shirt slits would have been visible with the shirt and tie still on.
You don't have to be a forensic expert to see that JFK's tie was centered between the collar, that the shirt slits were just below the interior collar band and parallel with the bottom half of the ends of the exterior collar band, and that any bullet exiting the shirt slits would have had to tear through the middle area of the tie knot. But there was no hole through the tie, only a small nick on the tie knot's left edge made by the Parkland nurses, which is why Dr. Carrico said he didn't see any nick in the tie nor slits in the front of the shirt until after the nurses began hurriedly cutting away JFK's clothing.
The SBT was a farse from the moment it was concocted.
