Jerry,
On it's own, CE-399 doesn't tell us much of anything. It has to be coupled with at least one other piece of evidence to have any evidentiary value. The same goes with pretty much all of the evidence. And that's why I haven't bothered responding to the OP.
So, basically you agree that there is not one single piece of physical evidence conclusively tied to Oswald which is of such significance that it beyond reasonable doubt clearly points to his guilt?
Could it actually be your position that all there really is are some individual pieces of physical evidence which perhaps can be tentatively linked to Oswald in some creative manner and require support from other similar pieces to construct a mere circumstantial case by making assumptions?
