Okay John let's take it a piece at a time. All of the physical evidence in the case which includes the bullet, fragments, and rifle that were found were linked to Oswald.
Ok, one at a time.
What bullet was linked to Oswald, and how?
What fragments were linked to Oswald, and how?
What is your evidence that Oswald owned, possessed, or fired the C2766 Mannlicher Carcano rifle allegedly found in the TSBD?
