It is also used by testimonial experts in the field as a useful tool
to alert them to areas about which they are likely to be questioned
in alcohol cases, as well as for its chapters on the current state of
the art with respect to alcohol testing, and the limitation and true
significance of reported results.
That last is a primary goal of the text: to provide reliable information
to all sides, to attorneys and expert witnesses alike, and to encourage
continuing discussion in this field about what constitutes appropriate
and responsible collection, testing and reporting of alcohol test values.
The offer by some experts of erroneous and unsupportable opinions, of
opinions that overreach and exceed the limits of responsible science,
is also a major theme of this text. It is the position of this text that
the courts, the public, and all parties to litigation which involves alcohol
tests, have a common interest in the proper interpretation of alcohol
test evidence and in the offer of opinions which properly reflect the
true significance of given test results in given cases.

PART I Alcohol Consumption, Human Physiology & Individual Differences
Five chapters explain in detail what happens to alcohol in the
human body, how the blood alcohol concentration (BAC) comes into
being and is present for testing in breath, blood and other body fluids,
what factors affect the rise and fall of the BAC (and reported values),
the methods and limitations of predicting probable BAC values after
drinking (the Widmark study and its impact on drinking/driving
evaluations), the importance of individual differences in general and
between men and women. The attorney's real understanding of alcohol
tests, and of the true significance of given results, begins with this
material.
PART II An Introduction To Basic Alcohol Calculations
Three chapters take the reader on a step-by step explanation
through the intricacies of performing appropriate calculations in specific
alcohol cases. In these chapters is the key to understanding how and
why experts perform erroneous calculations (more common than one might
think), and when opinions overreach based on the facts known and available.
The derivation of each essential factor involved in proper Widmark calculations
is explained, along with the identification of erroneous and
incorrectly-used factors (by some experts and laboratories).
Methods are given in detail for the Office Use of such calculations
by attorneys to evaluate the facts of cases and to assess the credibility
of the "drink count" histories received from clients.
PART III Blood Alcohol Testing and Reporting
Five chapters take the reader through blood alcohol testing
procedures, problems and issues, both traditional and more modern
methods. This material forms the basis for later chapters on the specific
depositions and trial testimony of laboratory technicians and other
experts (that later material puts the meat on these bones). One chapter
treats in detail the conversion of serum/plasma alcohol values to whole
blood values. [Note: while serum/plasma is the most common
alcohol-testing method in use in hospitals, clinics and many other laboratories,
most criminal statutes commonly require whole blood values, and
impairment issues (criminal and civil) are commonly reported and discussed
in terms of whole blood values.] Reading and understanding chromatograms
(the print-outs of "gas chromatographic devices") is also
discussed, as is the "Peak Height" equation. The reliability,
significance of, and problems with post-mortem alcohol test values is
discussed, as are the typical practices of Coroners and Medical Examiners.
A separate chapter (new in 2000) discusses in detail one of the most
controversial aspects of the testimony of blood-alcohol tests expertsperforming
Retrograde Extrapolations.
PART IV Breath Alcohol Testing and Reporting
Seven chapters provide an overview of breath-testing,
the inherent problems in the conversion of breath to whole
blood values, "harmful" overestimates of true BAC by breath-test
devices in certain cases, specific kinds of breath-test devices (basic
theory and operation), the role of Simulator Devices and Simulator
Solutions, and the significance of deviations from the "target
value". Special attention is given to operation and theory of the
Intoxilyzer 5000 (in use in many jurisdictions).
PART V Basic Mathematical & Scientific Concepts, Terms, Measurements
In Alcohol Testing Literature and Reports
Seven chapters treat this area, one of the most troublesome
for attorneys, and one encountered at every level of the civil and criminal
litigation of alcohol-test cases. Basic alcohol test terms (scientific
and mathematical), measurement units, conversion charts (helping you
to convert equivalent but different expressions of alcohol concentration
into "% BAC"), chemical and mathematical concepts, the concept
of "% error," understanding the calculations of experts, identifying
skewed science, and explaining the specific importance of Replicate
Testing (new chapter, 2001)-all are designed for attorneys, and intended
to walk attorneys through these complex areas, and to serve as a resource
(a place to go for answers) when new material is encountered and must
be interpreted.
PART VI Breath Test Results In Criminal Cases; Pre-Trial Challenges
Five chapters deal with pre-trial challenges, pre-trial appellate
review of questionable statutory language, initial considerations on
motions to dismiss, challenges to new or expanded use of roadside breath-testers,
with lengthy transcripts indicating the practical problems one encounters
in such proceedings (working with courts pressed for time and courtroom
space, and back-logged trial lists). The transcripts here are examples
of the difficulties experienced when specific goals are not clearly
defined by counsel at the outset and then pursued in an orderly fashion
by the lines of questions put forth; when terms are not clearly defined
at each stage of testimony; and when poorly prepared (or examined) expert
testimony is offered.
PART VII Evaluating Alcohol Test Evidence In Civil Cases: Getting
the Most from Depositions
Five chapters, with extensive deposition transcripts included,
demonstrate for attorneys why their own careful preparation before a
deposition is so important; why goals and a "plan" should
be set up and followed (pointing out why the order in which questions
are asked can be so important in many cases); discussing why depositions
of the technicians themselves (the ones who performed the tests) can
be so important, rather than relying only on testimony of a supervisor
or director; and providing a review of the transcripts to show the later
importance of "unasked questions" and areas not pinned down.
This material also provides the deposition of a local Medical Examiner
(one who was not a Board Certified pathologist or toxicologist) to show
the common mistakes and "overreaching" frequently encountered
when M.E.'s and Coroners are deposed or testify.
PART VIII Preparation & Testimony of the Expert Witness in Alcohol
Test Cases
Eleven chapters-and one of the most useful parts of the book for
both Attorneys and Expert Witnesses alikethese materials provide
detailed examples and demonstrations of the proper and improper preparation
and use of expert witnesses in alcohol cases (but the lessons outlined
here often apply to the use of expert witnesses in all kinds of casesnot
just alcohol-test cases). We see specific examples of erroneous
expert opinions in both typical and exceptional alcohol-test cases.
The so-called Chappaquiddick case (drowning of Mary Jo Kopechne), and
the William Holden and Natalie Wood deaths, for example, are used to
show how unsupportable opinions are too often offered on the basis of
a later post-mortem alcohol value. Guidance for the preparation of your
own expert, for preparing the witness properly for the qualification
phase of his/her testimony ("effective" qualification--not
just questions aimed at obtaining admissibility of the opinions to be
offered), and matters to explore before you initially consult your expert
in a given area are all discussed in detail. Examining biased, difficult
or evasive experts; tips for prosecutors for examination of defense
experts in criminal cases; a new chapter (2001 Supplement, due out in
Fall) on the admissibility of expert testimony and the impact of Daubert,
Joiner, & Kumho, with attention to forensic science testimony
in particular-are all included. A demonstration transcript and chapter
on effective qualification of the expert; a chapter on "defining
terms" as an important tool for introducing on direct the substance
of your position or defense (before turning to the specific case facts
or opinions); more cross-exam tips for prosecutors faced with difficult
defense experts; and a guide to general cross-examination of blood alcohol
experts.
The two volumes also include numerous charts and Figures to make complex
concepts more readily understandable to laymen, as well as Appendices
and a helpful Index.
