Do we need to know the height of the back
wound?
February 2001
One of the disappointing aspects of the JFK case is the
endless confusion that surrounds the medical evidence. Even though a careful examination of
the medical evidence reveals that much of it is much more solid than is
usually portrayed, confusion persists. For this reason, I believe it would
be helpful to carefully consider which pieces of medical evidence are
expendable, i.e., are not really needed to get the right answer about the
assassination. Let us begin with the height of the back/neck
wound. This issue is contentious because the high position leads to a
downward trajectory through the neck and out the throat, and a logical
connection to Connally's back and thereby to the single-bullet theory (SBT),
whereas the low position leads to a horizontal or slightly upward track that is
often said not to hit Connally or create the SBT.
Let us grant for the sake of argument
that we cannot know whether the back wound was low or high. Let us then set
forth the other pieces of evidence that we do know, and see whether we can still
connect that bullet with Connally. If we can, the NAA and ballistic data take
over and tie the bullet conclusively to Oswald's rifle. If we cannot, we fall
into some sort of never-never land.
Here is the logical train of evidence without the height of
the back wound or the
inclination of the trajectory through the neck:
This simple line of reasoning
shows how the SBT flows naturally from the evidence with or without the the
height of the back wound. Thus, that height is not needed to understand the
assassination properly.
There's more, though. Once the conclusion in step 6 is
granted, the downward trajectory through the neck follows automatically, and
from it follows the high position of the back wound.
But we didn't need to go through all this trouble, because
two factors unambiguously place the back wound at the high position: (1) the
autopsy observation that the back wound was above the right scapula, and (2) Dr.
Lattimer's elegant drawing
of the downward line of injuries between the back wound and the throat
wound. So two independent lines of reasoning establish the high position of the
back wound.
