Every Florida DUI conviction rests on a number the State calls settled science: a breath reading, a blood result, or a score on a set of roadside exercises. It is not settled. Each one is a chain of assumptions the State has to prove and usually cannot. I wrote The Florida DUI Trial Manual to put the method for taking that science apart into the hands of the lawyers who try these cases.
What the book is
It is a working reference, not a treatise you shelve and forget. In plain English it explains the forensic science behind the breath machine, the blood vial, and the field sobriety exercises, and then shows how to challenge each piece in a Florida courtroom, from the first discovery request to the closing argument. Inside:
- The forensic science of breath, blood, and field sobriety testing, explained for trial lawyers
- Measurement uncertainty, retrograde extrapolation, and David Ball’s rule-out method, adapted for the Florida DUI case
- Worked cross-examinations of the blood analyst, the breath-test witness, and the arresting officer
- Discovery, Daubert, and suppression, with Florida authority throughout
- Two hundred cases, the current chapter 11D-8 rules, and a complete motion and form set
Who it is for
I wrote it for two lawyers. The first wants to stop taking the State’s science on faith and start testing it. The second would rather hand the science to someone who lives in it. Other attorneys already bring me into their DUI cases to read the forensic file and challenge it; this book is that same method, on paper. If the number is the whole case, the manual will help you work it, and if you would rather refer it, my door is open.
How to get it
The ebook is available now on Amazon. You can read a free sample on Amazon first, then keep the whole thing on any device. The hardcover edition is coming soon.
The State’s number is not the last word, and it was never meant to be read on faith. You’re better Safir than sorry.
