I rely on the evidence as presented by the WC and supported by the HSCA. If you believe they have "over exaggerated" the evidence then present evidence of that "over exaggeration" instead of just questioning the evidence and nitpicking ad nauseum.
Actually, this entire forum is evidence of the fact that the WC and HSCA over exaggerated the evidence. That's why we are still talking about this case 55 years later.
Where, when and by whom was "evidence of such screw up" presented? So far, in this thread, all I have seen is a classic "could have happened" LN argument.
It's in the OP.
No, it is not in the OP. You have not presented a shred of evidence to support the claim that postal workers simply screwed up when they gave Oswald a package addressed to Hidell?.
What is in the OP is an example of how postal workers can screw up combined with your "it could have happened here also" argument
