No one suggested that.
Would they mark keys and hat and not the casings?
??...Of course not.
As for the casings, my Glock throws the casing about six feet to my right and about two feet back.
Absolutely, it's why I said, they'll test the ejection pattern...
Begs the question:
Would 3 casing, ALL within a couple of feet from each other, like the markers at the shooting scene next to the body, not depict the close proximately of where they were fired from?
??
I never once said the cones did not mark casings. I said they may be markers on other evidence also.
