- Until a few years ago, those attorneys who attempt to defend a client who is having against drunk driving charges were general practitioners. These attorneys had little, if any, understanding of the nature of the offense. They were not familiar with such methods of DUI investigation such as as field sobriety tests, and seminars on how to defend these clients were almost completely lacking.
The most important thing was that, defense lawyers doesn’t know anything about the complexities of blood alcohol analysis, whether of blood, breath or urine. They don’t know the answers to the following questions that how does the Breathalyzer work? What does infrared analysis referred to? What is Gas chromatography? How is the metabolism of alcohol takes place in the human body? What is the "Widmark’s formula"? what is Hematocrit? What is "retrograde extrapolation" and how does it work? What are those physiological variables that can occur between individuals? What are those medical conditions that can effect a breath reading and how? What could happen if in case blood samples ferment or coagulate?
There is an involvement of knowledge of such highly technical fields as physiology, organic chemistry, physics, biophysics, electrical engineering in the chemical analysis of blood, breath or urine but these are the subjects that are far beyond the experience and training of lawyers.
