How would it show foreknowledge of the motorcade route?
~Grin~
Odd that you should ask, Mr Smith. Why, only a few short days ago you had no difficulty in seeing the linkage------------you criticized my hypothesis on the basis that Mr Oswald would not have had enough foreknowledge of the motorcade route to make the experiment with the Nixie parcel viable:
If he learns on Monday or Tuesday that JFK is passing the building, then there would be a remote possibility he considered mailing the bag there instead of transporting it himself but there would be no guarantee that it would arrive by Friday. And why do a test run to a different address with so little time?
As I have several times gently pointed out, this is the real reason you have tried (unconvincingly) to write the Nixie parcel off as a random hoax: evidence of nefarious intent on Mr Oswald's part is fine, but only so long as the timing does not threaten the Lone Nut scenario.
A Mr Oswald sending himself a heavy brown paper bag, but doing so in a way that suggests game-playing with the postal authorities, would suggest a Mr Oswald making plans for something clandestine that would involve the use of a heavy brown paper bag. That this would require more lead-in time than you are comfortable with is a problem for you, not me.
By the way, you dodged my question about
how a random hoaxer could have known to write the name and address in a way that even you have to admit looks like Mr Oswald's handwriting. Still trying to figure this little conundrum out, eh?
