If a cop doesn't show, you will have the charges dismissed. Happened to me when I got a ticket in HS and the cop was an asshat. He said if I went to court he would tell the judge I was going faster than what the ticket stated. There were like 20 of us that were pulled over by this guy and he did not show at court. We had our charges dismissed and as we were leaving the courthouse he was rushing in the door. We all laughed at him.
