Is it a traffic ticket? When you first show up, no police officer will be present - that's called an arraignment. You can plead guilty there, but why? Plead not guilty, waive time, and set it for a court trial. If the cop doesn't show up, case dismissed. Otherwise, hire an attorney who can negotiate for you.
