But much more should be argued. For one thing, photo-radar raises questions of due process. When a police officer pulls you over for a traffic offense, you can defend yourself effectively in court at a later date because the circumstances remain fresh in your mind. It is important to consider factors such as traffic and weather, to which the driver might have been reacting. Moreover, passing strangers who might be witnesses to the alleged infraction will be lost forever to the mists of time.
Some states try to solve the 'memory problem' by mailing citation as quickly as possible.
This solves nothing. Yet remembering such circumstances is precisely what you must do to defend yourself in court against a photo-radar ticket. In short, photo-radar denies you the reasonable opportunity to defend yourself adequately in court. You are further denied the right to face your accuser. Indeed, photo evidence is often not included in the mailed citation but must be claimed, usually at the office of the issuing agent.
