My problem with the pre event set up of Oswald is the MC riifle with misaligned scope. The only way to really explain that is to suggest the conpirators, haviing waited until the very last night, of Thursday night in the middle of the night, to steal the rifle, thus having not much time to test fire it, and thus realize the scope was wildly off in the elevation, without the shim undere the mount to correct for that.
This presumes of course that Oswald actually DID order the riifle, and the FBI and or CIA knew he had the rifle, possibly thru information from Georger DeMorhenschildt, and or Mrs Paine who imo,were very likely CIA "assets" at the least, and had been assigned to observer Oswald as a potential USSR spy returning to USA with another potential USSR spy, his wife, Marinna. The rifle may have been actually used by Oswald to shoot one shot at Walker, and once that became known, probably by DeMorhenshildt, that's when the pre set up really begins.
If this is the correct scenario, then the reason not to have stolen the rifle from Oswald, until that VERY NIGHT, or in the very early hours of Friday morning, was to minimize the risk that Oswald would discover his rifle missing. This applies to his boarding house as well, which is also where Oswald may have kept his rifle instead of in the Paines garage.
Perhaps the reason for Oswald to be wishing to return to his boarding room after the shooting, apparently asap, is that it was to check to see if his worst suspicion were true, that his rifle may have been stolen. Upon finding that to be true, is why aOSwald DEPARTED in haste, from his boarding room, with a revolver, and his original destination may have been towards Jack Rubys house, rather than the Texas Theater.
