Sounds like reasonable doubt. There’s a reason for those standards.
Not “better analyzed”, just much weaker criteria. Photos with no provenance stashed in a briefcase for 30 years and no disclosure on how many points matched or where they were.
By "no provenance", you mean some scenario like no one stood guard at "Rusty" Livingstone's house for 30 years to prevent the photos being planted, or "Rusty" (who was the DPD's photo-developer) fabricated the trigger-guard photos before he sealed the briefcase.
The provenance is about as good as it gets within normal reason. The briefcase was in "Rusty's" possession for all that time. He didn't even know the potential of what was in the case; his nephew Gary Savage brought the material forward. Too bad for your hero-patsy Oswald that whenever evidence that's better-quality shows up or when forensic techniques (ballistic testing; 3D trajectory analysis) improve with science done by professionals, it always reinforces the LN scenario.
