Huh? Why would McCamy need to repeat what Kirk just spent considerable time explaining, he simply adds that the particular chip on the rifle in the backyard photo was in the same place as the one in evidence.
This is not ambiguous to anyone without an agenda to read things that aren’t there:
“the
Panel's forensic photographic specialist considered this mark to be a random patterning sufficient to warrant a positive identification.”
That’s Cecil Kirk. It’s not anybody else.
So essentially a random sized chip in a random place by definition becomes a distinguishingly unique feature.
Because it tilts the scales. Because moon craters. Because wishful thinking.
