Yes.
We've provided everything a prosecuting attorney would ask for when trying a murder case.
Were there witnesses that saw the shooter? Does our suspect match their description?
Yes, and yes. Multiple witnesses saw the gunman, Oswald fits the descriptions provided.
Can we place the suspect at the scene? Does he have an alibi during the shooting?
Yes we can definitively place him in the depository. Better than that, he was definitively at the sixth floor window within hours of his prints being lifted from boxes arranged around it. He had no verifiable alibi.
Did we recover the murder weapon? Can it be conclusively linked to the shooting?
Yes, a weapon was recovered from the same window we know Oswald was at. Yes, that weapon links to every recovered shell and fragment large enough to have rifling marks on it.
Can we link the suspect to the murder weapon?
Yes. Every available piece of evidence points to Oswald and only Oswald. The order form, the money order, the PO box, the Hiddell ID, the backyard photos, the statements of his wife, the statements of the Paines, all link Oswald AND ONLY Oswald to the rifle.
Can we come up with a plausible explanation for how the weapon got to the murder scene?
Yup. Paper bag, prints all over it, fibers inside it, "curtain rods" lie, Buell Fraser's statements, Linnie May Randall's statements, all paint a pretty plausible explanation for how the rifle got to the depository.
Did the suspect leave prints or other identifiable markings tying him to the crime?
Yup, palm print on the rifle, fingerprints on the rifle, fingerprints in the snipers nest window, fingerprints on the paper bag on the sixth floor, fibers in the paper bag, fibers in the butt of the gun, all point to Oswald.
Did the suspect show consciousness of guilt after the crime?
Yup. Fled the scene within 3 minutes, armed himself, shot a cop, snuck into a theater to get off the street, attacked other cops on the theater.
This is just scratching the surface. There is so much more than this, these are just the bullet points. You can attempt to pick holes at this, but you can't make any of it go away, and more importantly, you can't produce a shred of evidence implicating a different shooter.
