Re: Lieutenant J.C. Day and the Pinkston memo.....
It's clear to me that the Pinkston memo (seen below) is referring to the PALMPRINT that was discovered by Lt. Day on the rifle.
Why do I say that?
Because the memo
three different times specifically says "PRINT" (singular) and not "prints" (plural).
If the memo was referring to the trigger guard prints, it would very likely say "prints" (plural), or at least it
should, because we know that Lt. Day saw
two prints on the trigger guard (and he testified to that fact).
