Visitors to Judge Gresh's court will receive fair treatment at the podium regardless of the violation. He says, "I always try to consider that it could be me behind the podium, or a neighbor, and always try to treat people with respect and courtesy. Most municipal violations are in some ways like small claims court of criminal law, so they are not major crimes of any kind, they are just the normal infractions that occur in life."
