This presentation is designed to inform the
attendee what purpose the aluminum strip that
he/she received at registration serves. This
presentation will also inform the attendee on
the machining process in manufacturing the
aluminum strips.
Evan Thompson is the AFTE member who arranged
for these items to be made and donated his time
and energy in preparing them for distribution at
the AFTE 2007 conference.

To date over 420
examiners (including the original 67
participants from Brundages initial study) from
15 countries have completed the examination of
bullets knowns and unknowns fired from ten
consecutively rifled Ruger P-85 pistol barrels.
In addition to examiners examining the bullets
using conventional comparison microscopy, the
bullets were also examined using SYCLOPS, ALIS,
ISBIS, and FTIs new BulletTRAX-3D ฎ
This update is provided pending submission of
the data to our AFTE Journal for consideration
of publication by mid-summer. An error rate was
developed as part of the research project and
will be included with the submitted data.

AFTE and the NFSTC have been working together to
develop and produce a media based training CD to
complement and enhance the existing AFTE
training materials.
The use of a technology-based training (TBT)
approach offers an engaging format to capture
attention and to increase trainee comprehension.
It is anticipated that this approach will
streamline and standardize the training of
firearms examiners, thus allowing for the
effective allocation of available funds to reach
the maximum number of interested parties.
The purpose of this presentation is to provide
an update to the membership on the progress of
the material and present a beta version.
Some additional information will also be
provided regarding the NFSTC and products of use
to the AFTE membership and their laboratories.

An extensive
comparison microscopic study has been conducted
to test the validity of the science of 3-D
fracture matching. In addition, to address the
error rate prong of the Daubert standards, a
series of proficiency tests was developed. Four
hacksaw blades were used to develop fourteen
tests, each with a randomly generated number of
matches and randomly generated matching item
numbers. Most tests were made from a single
blade, each test was different, and each test
was then validated. To date, we have a response
rate of approximately 96% and received results
for 13 out of the 14 tests and multiple results
for some tests.
This presentation is being made to request
assistance from the membership to participate in
the proficiency testing program. A final paper
will be submitted for publication after test
results have been received to provide an error
rate from a sufficient population of the
relevant scientific community.

The words we use to describe our
work, what we observed and what opinions we
derived from these observations should be chosen
with great care.
Our personal biases (we all have them) can
quickly creep into our reports and testimony as
evidenced by our choice of words.
This brief presentation will illustrate some
examples of language this writer has observed
and given much thought to over the years.
It is hoped that the attendees will do likewise
and make every effort to craft their reports and
testimony in a concise and objective manner in
all their future efforts.
