Appendix 2: Definitions (some
Caliber: American weapons use inches for caliber, whereas
Europeans use mm. For example, the .30-.30 has a caliber of 0.30 inches
= 7.62 mm.
Carbine: usually shorter than a rifle and of lower
Photogrammetry: determination of the geometric properties
of objects, based on photographic images.
Stereophotogrammetry: estimating the 3D coordinates
of points on an object via measurements from two or more photographic
images, taken from different directions.
Appendix 3: Ammunition terminology
Blank: cartridge without the bullet
Bullet: just the projectile, which may have a jacket
(not shown in the illustration)
Cartridge (or round): the whole ensemble, as seen before
Case: also known as casing or shell or hull—what is
left behind after the projectile leaves
Slug: the projectile, a term most often used with shotgun
A modern cartridge consists of the following:
- the bullet itself, which serves as the projectile;
- the case, which holds all parts together;
- the propellant, for example gunpowder or cordite;
- the rim, part of the casing used for loading;
- the primer, which ignites the propellant.
Appendix 4: Citations for the
- “Reexamination of Acoustic Evidence in the Kennedy Assassination,” Committee
on Ballistic Acoustics, National Research Council http://jfk-records.com/NRC_Science/science.htm
The committee drew these conclusions and made these statements:
- Analyses of the acoustic evidence do not demonstrate that there
was a grassy knoll shot, and in particular there is no acoustic
basis for the claim of 95 percent probability of such a shot.
- The acoustic impulses attributed to gunshots were recorded about
1 minute after President Kennedy had been shot and the motorcade
had been instructed to go to the hospital.
- Therefore, reliable acoustic data do not support a conclusion
that there was a second gunman.
- …features of the recorded sounds strongly suggest that the open
microphone was not in Dealey Plaza at the time of the assassination.
- The impulses selected for the BRSW study were not always the
- …weak spikes on the Dictabelt often are selected to correspond
to strong patterns in the test patterns, and vice versa.
- No siren sounds are heard on channel I at a time when they should
have been heard by an open microphone in the motorcade; sirens
are not heard for approximately 2 minutes….
- James Bowles, police communications supervisor at the time of
the assassination, suggests that it [the stuck microphone] was
on a motorcycle parked at the police command post near the Trade
Mart, where it would be natural to have adjacent police radios
tuned to different channels.
- Furthermore, even if it were granted that the hypothesis of randomly
located impulses on relevant portions of the tape were in serious
doubt, it would not follow that the alternative of gunfire from
the grassy knoll was convincing. All plausible alternatives to
both of these hypotheses would have to be eliminated, and no convincing
effort has been made in this direction.
- …the "hold everything" segment of channel II is present
on channel I at the same location as the acoustic impulses [i.e.,
- These different forms of evidence are all compatible with the
recordings [of sounds] made at the same time [i.e.,“…Hold
everything secure…” and the suspect gunshots], and some are
incompatible with the hypothesis of later superposed recordings
by audio or direct electrical coupling.
- …the Committee on Ballistic Acoustics unanimously concluded that
the acoustic impulses attributed to gunshots were recorded about
1 minute after the President had been shot and the motorcade had
been instructed to go to the hospital….

Appendix 5: The Sellier article
(in German) on bullet deflection
The angle of deflection for three different bullet types, through aluminum,
brass, and steel of thicknesses 1/16” and 1/8,” ranged from
30 to 66 º, with the highest value for brass. For wood, the corresponding
angles ranged from 12 to 36 º, depending on the bullet type. Interestingly,
in wood the 7.65 bullet gave the highest deflection (of 36 º). Ribs produced
rather little deflection. None of these data, in my opinion, seem pertinent
to the case of a bullet striking a skull, so it is not clear why Thomas
cites this paper at all. Sellier also cites work done on deflections
from concrete, asphalt, and grass. These data might be germane to the
bullets that struck the street surface in Dealey Plaza, but Thomas does
not open that door and I have likewise not explored it. Interestingly,
Sellier cites work by M. Jauhari: “Bullet ricochet from metal plates,” J.
Crim. Law Pol. Sci. 60, 387-394 (1969). Since this paper is in English,
and appears to be the actual source of the metal deflection data (discussed
by Sellier), it is odd that Thomas did not explicitly cite it. Another
English language paper not cited by Thomas (but present in Sellier’s
bibliography) is this one: “FBI: Bouncing bullets.” FBI Law
Enforcement Bulletin, S. 2-6 u. 20-23. Washington, Sept./Okt. 1969. This
is the paper that tests deflections from concrete, asphalt, and grass.
One can only wonder if that work was triggered in part by the bouncing
bullets in Dealey Plaza.

Appendix 7: Sources of uncertainty
in the timelines for the audio tracks
- The recording stopped, typically after 4 seconds of silence (in either
- Skips or repeats occurred during recording (Ch-2, Gray Audograph).
- Playback caused skips or repeats (Ch-2, Gray Audograph).
- A standard phonograph table (for Ch-2) was required for playback.
- The police tape playback speed (Ch-1) was 5% too fast.
- Crosstalk events might be misidentified.
Appendix 8: A viable sequence
of pertinent sounds
Note: See details in Table 1 by LG (reference 5 of my Appendix
4)—or Table 1 or Table 2 from O’Dell (shown in this review).
Note that GO (by Curry) is not a crosstalk. CHECK1 and CHECK are two
different utterances at two different times, so they cannot represent
crosstalk. ATTENTION was a deliberate simulcast, but it is not very useful
for establishing a timeline because it occurs so late. The suspect shots
overlap with HOLD on Ch-2. They are not heard on Ch-1. Thomas’s
notation is used here, except for CHECK1, a label that was introduced
by LG in order to distinguish it from CHECK. Red arrows indicate authentic
crosstalk sounds. Bellah actually consisted of two closely spaced utterances,
but only one is shown here. This sketch is not designed for precise intercomparison
of the two channels (for either the times or the intervals), nor is it

Enemy of the Truth: Myths, Forensics and the Kennedy Assassination is so
comprehensive in its approach, this work should be used in the instruction
of all new crime scene investigators nationwide. William
