Then your arguments are lame because you aren't making any valid arguments at all.
Not nearly as lame as all of your excuses for conflicting and inconsistent evidence.
What was reported at the scene does not prove that the shells in evidence aren't the shells found at the scene.
Not necessary, because you can’t prove that they are.
The argument that Poe did indeed mark the shells is not more credible than the argument that he didn't mark them.
Poe said that he marked them until he was presented with shells he couldn’t find his initials on.
I'll rephrase my question. Do you believe the shells found at the scene were automatic shells?
I don’t know what shells were found at the scene. That’s the whole problem — it’s unknowable. Even if Gerald Hill was the idiot you need him to be, it’s still unknowable.
