Your point? The paper bag was matched to paper used at the TSBD. Oswald no doubt decided to kill JFK on Thurs. Nov. 21 when told about the motorcaid to go past the next day. Being a skinflint and a kind of MacGyver minimalist at getting maximal results with the absolute minimum of material, he went home that night (unusually early, as he usually did this on a Friday) with W.B.Frazier, saying he needed to get curtain rods for his apartment. A minimal lie which would cover the long package he EXPECTED TO HAVE the next morning. He no doubt took a lot of folded paper and some tape home with him from the TSBD, and made up the rifle package in the garage that night with it.
Clearly he went home on Thursday, just to retrieve the rifle. Had he planned the assassination before that Monday, he wouldn't have had to make an extra trip home, which was surely a hassle. He could simply have brought the rifle on Monday AM, Nov. 18, and let it cool in a hiding spot in the TSBD for five days.
For those who think Oswald was a patsy with real curtain rods, he wasn't a window-treatment kind of guy, to say the least (save that for David Ferrie). Nor did his window need curtain rods. It already had them, and had the same ones it always had, according to Roberts.
Oswald's excuse was unusually lame, as even if Oswald had needed curtain rods and had some new and exciting ones, he was the kind of efficiency-of-action guy to have waited till a Monday when he normally went to Oak Cliff in the evening, for the first time after a weekend at Irving. Doing it Friday for installation the NEXT Monday (since he went home with Frazier from the TSBD on Friday evenings anyway) was particularly bizarre. If he was going to leave curtain rods in the TSBD over the weekend anyway, why make a special trip to bring them into Dallas on a Friday? If he was going to stay over the weekend, perhaps to fondle his new curtain rods, why not tell Frazier this, so Frazier would NOT be expecting to bring him back to Irvine, as usual for a Friday, that night after work? He had stayed in Oak Cliff for a weekend once before. Frazier was used to being told he wouldn't be going back on a weekend when Oswald wasn't going back. Again, Oswald was not a type to waste money on bus fare if there was ANY alternative.
