If they intended to frame Oswald, they only needed to plant one rifle and three spent shells.
Obviously other snipers wouldn’t/didn’t leave rifles behind.
If they intended to frame Oswald, they only needed to plant one rifle and three spent shells. I believe the "They" in this case could have been Lee Oswald himself..... He was playing the role of an ATTEMPTED assassin....
He thought that if Castro believed that he had tried to shoot JFK, then Fidel Castro would grant him asylum in Cuba.
Thus Lee wanted it to appear as if he had actually fired the carcano at JFK.... (And obviously millions of people do believe that)
But in reality that old carcano was nothing but a stage prop and it never was fired that day....In Fact the carcano was already hidden beneath the pallet of books in the NW corner of the sixth floor at the time JFK was ambushed....And Lee was in the first floor lunchroom when JFK passed by the entrance to the TSBD.
