So you keep claiming. I don't know why.
Yes. What gave you the idea that the US postal service would act as an uncompensated COD collection agent for Railway Express?
I was wrong to say the revolver was shipped to the post office. In actuality, a notice was placed in Oswald's post office box informing him that he would have to go to the Railway Express office on South Houston Street in Dallas to retrieve his item.
The paper trail related to Oswald's purchase of the revolver under the name of Hidell is solid.
Once Oswald received the notice in his P.O. Box, he presumably took a bus to the Railway Express office and presented the notification card, paid the balance due ($19.95 plus shipping) and provided some form of Hidell identification.
The fact that Oswald had the revolver in his possession at the time of his arrest inside the theater ir further proof that he took possession of the revolver at the Railway Express office several months earlier.
