Every DUI case will of course entail the testimony of law enforcement and their anticipated recitation of the facts leading up to your arrest. However, the officer’s mere “opinion” that you were impaired can often be insufficient evidence to secure a conviction. It is for that reason, that law enforcement will typically employ a variety of scientific measures in an effort to support or bolster their self serving conclusions.
An effective DUI defense attorney needs to carefully examine all of the evidence in your case. But such a proper examination can only take place if it is coupled with a firm understanding of the scientific principles underlying the testing procedures used by law enforcement. When selecting an attorney, you should choose a lawyer who is passionate enough about his work that he regularly takes the time and incurs the personal expense to stay abreast of cutting edge developments in the law.
The identification of scientifically related evidentiary issues in your case is critical. It could lead to the reduction or even the dismissal of your charge. You should never simply assume that the evidence in your case was lawfully collected, properly analyzed or carries the proper foundation to be later admissible in court.
