Driving While Impaired: Confronting Defense Challenges & Guidance for Law Enforcement & Prosecutors (Criminal Justice, Law Enforcement and Corrections)

To fill that void, this publication provides an overview of the criminal justice system for people who will likely encounter it through their roles as expert witnesses.
