Brian Lowell Leininger

About me

I chose the field of DUI defense for many reasons.  I have a great deal of experience in all areas of the criminal law, and it is my opinion that more people are falsely accused of DUI than any other crime.  Many Judges and jurors assume a person is impaired if he or she cannot walk perfectly heel-to-toe on a line or stand on one leg for thirty seconds.  The fact is, most people cannot do these things after having nothing to drink.  Try to do theses things in your living room, then imagine trying to do them on the side of a busy street after being pulled out of your car by a police officer.  Additionally, I like the scientific aspects of this field, such as the effects of alcohol and drugs on the human body and the inability of breath testing machines to accurately measure a person's alcohol level.
