If the Carcano was there why the need for a composite photo?
The DPD took an in situ photo of the rifle at the bottom of the chasm that was formed by the stacked boxes of books. They snapped that photo at about 1:45 that afternoon..... But they soon realized that the in situ photo they had taken clearly showed that Lee Oswald COULD NOT have deposited the rifle during a hasty dash from the SE corner of the sixth floor to the 2nd floor lunchroom.
They knew that it would have taken several minutes to place the rifle in the bottom of that chasm, and then cover the top opening with boxes of books. They recognized that they needed to destroy the in situ photo they had taken and create another photo that would support the tale they were perpetrating.
If the Carcano was there why the need for a composite photo?The Carcano wasn't there.....The FBI had snapped it up and whisked it off to Washington DC at midnight 11/22/63. But the DPD did have many photos of the carcano so it wasn't very difficult to take a photo without a rifle in it and then place the rifle in the photo. But don't take my word for it... EXAMINE the official in situ photo for yourself.....
