So your evidence that this package demonstrates foreknowledge of the motorcade is that "it is extremely unlikely" that it "would not be singled out" among all the mail handled by the Dallas post office system. Got it. In other words, you have nothing except a baseless assumption. You don't have any actual evidence of the date this package was mailed. You don't have even have any evidence that Oswald mailed it except that the handwriting looks similar to you. You have no plausible explanation for why Oswald would send such a package to a nonexistent mailing address whether before the motorcade route was announced or after. Oswald already knew that the FBI was aware of his connection to the Paine residence. He can easily carry a folded paper bag under his jacket (as he did).
~Grin~ Is this supposed to be a refutation, Mr Smith?
We now have you committed to the view that a parcel addressed to "Lee Oswald" after the assassination WOULD have been treated as just another regular postal item because that name wouldn't have triggered the least recognition in Dallas postal workers
There is no apparent reason for Oswald to undertake this exercise in futility.
Except.......... there is, the one I've offered. The fact that your intellectually dishonest (and increasingly desperate) attempts to refute it have been a pitiful failure is no more than a fun fact worth noting!
If I've got things wrong with my hypothesis for the Nixie parcel, then it looks like it's going to take someone that bit smarter than you to show me where.......
And even if all your baseless assumptions were correct (i.e. that Oswald mailed this package to a nonexistent address prior to the assassination to test whether the FBI was monitoring his mail to the Paine residence), that still wouldn't support the conclusion that this demonstrates foreknowledge of the motorcade route. It would merely suggest that perhaps Oswald was thinking about mailing the long paper bag to that address to smuggle the rifle out for some unknown purpose.
"For some unknown purpose". Why, I do declare this is your funniest one since you argued that a paper sack would be needed to carry a concealed pistol. Talk about the desperation of the self-cornered Warren Gullible!
Maybe he was going to give Walker another try or someone else. He was a nut job. It seems like he was intent on using his rifle to commit some act of violence that would not have ended even if the JFk motorcade had never come by the TSBD.
"Some act of violence" lol
Keep the escapological nonsense coming, Mr Smith, it's high entertainment!
