The short answer is that yes, cases are won all the time. Many cases are won in the pretrial investigation state before ever going before a jury. A good Florida DUI defense lawyer will investigate all of the facts of the case to determine where the weaknesses are, and then develop the case from those points. It is often a DUI defense lawyer's discovery of issues in a Florida DUI case that brings the prosecutors to the plea bargaining table. If you haven't already, consult with a lawyer to determine what defenses might be available in your case that could cause a favorable, non-DUI, plea bargain, or result in victory through litigation or trial.
