It's not my story.
Yes it is... You made out of "fibers that are similar to those of Oswald's (arrest) shirt", which is a rather meaningless observation since most shirts are made from similar fibers, into "fibers from Oswald's shirt", which is simply a lie
It is their story that the FBI needed to coerce a witness into confirming that Oswald wore the arrest shirt because of the fibers found on the rifle.
You mean Bledsoe?.... Name me one other witness in any case where that FBI actually brought a piece of evidence to their home prior to their testimony?
Of course that FBI had a problem. They had only tested Oswald's arrest shirt (and no other) and had claimed that the fibers found on the rifle were similar, only to then find out that Oswald possibly wasn't even wearing the arrest shirt in the morning after all.
If those fibers don't have evidentiary value or link Oswald to the shirt, it begs the question why that evidence would need to be faked.
What evidence was faked?
Here's the story that Hoover was propagating.... ( a damned lie )....
A 12-1 article in the Washington Star by Jerry O'Leary, a writer more than friendly with the FBI's Deke DeLoach, and someone upon whom the FBI regularly relies to get their stories before the public, declares: "PIECE OF OSWALD'S SHIRT FOUND SNAGGED IN RIFLE." It then goes on to claim "A fragment of Lee Harvey Oswald's shirt was snagged in the rifle that killed President John F. Kennedy, the FBI report of the assassination states. Disclosure of this evidence against the 24 year-old Oswald, himself slain two days after Mr. Kennedy's death, is regarded as one of the most solid pieces of evidence of his guilt. Officials said wisps of brown shirt material were caught in metal parts of the 6.5 mm Italian-made carbine found on the fifth floor of the Texas School Book Depository Building a few minutes after the fatal shots were fired on November 22. When Oswald was arrested two hours later, he was wearing a brown shirt of the same material. Oswald claimed he had changed his shirt in his rooming house after leaving the assassination area, but this proved to be untrue. FBI Crime Lab technicians determined by microscopic and other scientific means that the fragment of shirt material came from the shirt the ex-Marine was wearing."
The story presented to the trusting and grieving American public at the time (December 63) said that The FBI had found a tuft of fibers on the butt plate of the TSBD carcano. The FBI said that the carcano belonged to Lee Oswald and it was the rifle used to kill President Kennedy. They also said that the tuft of fibers matched the shirt that Lee Oswald was wearing at the time of the murder, and that was the same shirt that Lee was wearing at the Texas Theater.
The entire tale is a damned lie.....
