But back to the thread - IF DNA testing of the cases is possible it COULD provide some answer .Because of the 5 bullets he allegedly did not handle . Unless he used gloves.
I'm not really sure how that could help.
If JB's DNA was found on the bullets, then he could say he had handled when they were purchased, or at some point since then.
If his DNA wasn't found, then as you say he could have worn gloves.
Or maybe the bullets were just tipped out and not touched at all, therefore no DNA traceable.
In any event, do they even still exist?
