obliquity and the evidence for a frontal shot.

[Herbert Blenner]

Anyone read this, very interesting theory.
Certainly pours a lot of cold water on the TSBD as the source of the head shot.

Any comments, criticism , etc.
It does take a bit of reading and digesting.

The author is not a technologist as evidenced by their misuse of the technical term angle.

I quote him.

"The precise location and angle of wounds to the head: Parkland vs. Bethesda?"

"An accurate reconstruction of the precise locations, sizes and angle of the wounds to the head of President Kennedy is of paramount importance, of course, because it can tell us a lot about the origin of the shot and the weapon of murder."

"Furthermore, a new terminal ballistics equation with a more precise and detailed distribution of kinetic energy of the oblique bullet and its fragmentation (rather than the less reliable and rough physical analysis of the "ballistic pendulum") along with experimental data, provide compelling evidence that highest degree of bullet's fragmentation occurs whenever impact of bullet on target exhibiting obliquity> 20° (with 60° as angle of biggest shattering!) is taking place."

A technologists recognizes that an angle measures the difference between two directions. So specification of any direction by an angle must include the reference direction of the zero-degree angle.
