One of those things that has eluded me for a few years is what precisely
was meant by "tangential" wound when Dr. Clark used that term to describe
the wound ON THE SIDE of the Presidents head.
I now believe I know what he meant by that term...He meant that the wound
on the side of the head was not caused directly by the bullet implying
that he did not think the bullet entered or exited there but, rather, the
wound on the side of the head was caused by the effects which were caused
because the bullet struck the head at an oblique angle and caused
secondary missiles to be created ( such as skull fragments etc)
Here is exactly what Dr. Clark said and how he defined the term
Mr. SPECTER - What, if anything, did you say then in the course of that
Dr. CLARK - I described the President's wound in his head in very much
the same way as I have described it here. I was asked if this wound was
an entrance wound, an exit wound, or what, and I said it could be an
exit wound, but I felt it was a TANGENTIAL wound.
Mr. SPECTER - Which wound did you refer to at this time?
Dr. CLARK - The wound in the head.
Mr. SPECTER - Did you describe at that time what you meant by "tangential"?
Dr. CLARK - Yes, sir; I did.
Mr. SPECTER - What definition of "tangential" did you make at that time?
Dr. CLARK - As I remember, I defined the word "tangential" as
being---striking an object obliquely, not squarely or head on.
Mr. SPECTER - Will you describe at this time in somewhat greater detail
the consequences of a tangential wound as contrasted with another type
of a striking?
Dr. CLARK - Let me begin by saying that the damage suffered by an organ
when struck by a bullet or other missile---
Mr. SPECTER - May the record show that I interrupted the deposition for
about 2 minutes to ascertain what our afternoon schedule would be here
because the regular administration office ordinarily closes at 12
o'clock, which was just about 15 minutes ago, and then we resumed the
deposition of Dr. Clark as he was discussing the concept of tangential
and other types of striking. Go ahead, Doctor.
Dr. CLARK - The effects of any missile striking an organ or a function
of the energy which is shed by the missile in passing through this organ
when a bullet strikes the head, if it is able to pass through rapidly
without shedding any energy into the brain, little damage results, other
than that part of the brain which is directly penetrated by the missile.
However, if it strikes the skull at an angle, it must then penetrate
much more bone than normal, therefore, is likely to shed more energy,
striking the brain a more powerful blow.
Secondly, in striking the bone in this manner, it may cause pieces of
the bone to be blown into the brain and thus act as secondary missiles.
Finally, the bullet itself may be deformed and deflected so that it
would go through or penetrate parts of the brain, not in the usual
direct line it was proceeding.
Testimony of Dr. William Kemp Clark
Frame 313 of the zapruder film confirms that the bullet struck the top of
the JFK's head at an oblique angle. Considering Dr. Clark did not have
access to the Zapruder film, his initial analysis was pretty good.
