Wasn't Oswald's "hidden" print found on the disassembled Carcano, and didn't the DPD or some other law enforcement agency detect and photograph some hard-to-make-out prints on its trigger guard on 11/22/63, and didn't a fingerprint expert take a close look at those photos years later and determine that the prints were Oswald's?
A single partial palmprint was sent to the FBI on an index card a week after the assassination.
Latona told the WC that the trigger guard prints were not suitable for identification purposes. Scalise told the HSCA that the the trigger guard prints were not suitable for identification purposes. 30 years after the assassination, some photos with no provenance whatsoever were pulled out of a briefcase and examined by Scalise, who didn't publish his work, or identify how many points of identity he found or where they were located.
Also, weren't some fibers from Oswald's shirt and/or the blanket in Ruth Paine's garage found on the Carcano?
Fibers cannot be exclusively matched to a specific item like a shirt.
