Someone who is truly and honestly neutral on what happened, is agnostic on what occurred that day in Dallas and has no set opinion on whether it was Oswald alone or a cast of thousands, would, on the bag question (and others), challenge every explanation as to what it contained and not just one. Viz., that it contained a rifle, that it contained curtain rods, that it contained a lunch, or that it contained something else. Each theory would be challenged.
But we don't see that here (or with the other questions). We have this challenge against the "bag had the rifle" theory but not challenges of the curtain rod or lunch or "something else" theory. This from the person who says he has no theory as to what happened (and isn't interested, he adds, in any one of them anyway). The intellectual inconsistency is obvious to everyone.
