It has always struck me as odd that LN'ers insist that the only time and manner of the rifle arriving was that morning.
Whilst it is possible that the witnesses, were all wrong, why does it matter when Oswald brought the rifle in??
Unfortunately, If a person accepts that it's possible that Lee did in fact bring the carcano into the TSBD at anytime prior to the coup, then that automatically means that he was guilty of murdering the POTUS. Since I believe that Lee was being set up as the patsy ....I can accept that he brought the carcano into the TSBD at some earlier time. ( Probably after hours when there was nobody around) BUT since the rifle was wiped clean of any prints, then "someone" other than Lee handled that rifle and wiped it clean before hiding it beneath the boxes of books. Who ever that person was they didn't want their prints to be found on that rifle. Lee wouldn't have cared because he was under the impression that he was playing a role very much like the role he played at Walker's. A role in which it appeared that he had
ATTEMPTED to shoot JFK but missed.
It's entirely possible that Lee took the rifle into the TSBD days before the shooting..... But That rifle was never fired on 11/22/63 ....
However..... IF Lee was the person who took the carcano into the TSBD it doesn't make sense for him to have left the blanket in a condition that made the blanket appear to have a rifle in it. If Lee had removed that rifle he would likely have simply folded the blanket and stowed it away with his other possessions in that garage.
