So, why are there TWO chains of custody and no tags on the shells from any of those in possession of the shells, Lt. Day included (DAY)?Easy-peasy. As easy as 3-2-1 in fact..
Three shell discovered shortly after the assassination at the sniper's nest window were ballistically traceable to Oswald's rifle to the EXCLUSION OF ALL OTHER WEAPONS IN THE WORLD.
Chain of custody?Two large fragments discovered the night of the assassination in the Presidential limousine were ballistically traceable to Oswald's rifle to the EXCLUSION OF ALL OTHER WEAPONS IN THE WORLD.
Chain of custody?One nearly whole bullet discovered in the hospital near Connally's stretcher on the afternoon of the assassination was ballistically traceable to Oswald's rifle to the EXCLUSION OF ALL OTHER WEAPONS IN THE WORLD.
What you call ”quibble”, the rest of western civilisation calls evidence with secured chain of custody and provenance. Without that, its pretty much worthless.Now you'll quibble over the claims and pretend the evidence isn't admissible because [whatever you can think of the moment] but all that evidence is admissible and all of it establishes Oswald's rifle was fired not only on the day of the assassination, but at the time of the assassination and at the Presidential limousine. To the EXCLUSION OF ALL PLACES AND TIMES.

These concepts was well established in the USA 1963 going decades back from that point in time.
Quibble, the new null?
