It's another money grab, using cops as tax collectors - always a bad plan.

One of the reasons that Photo Radar failed was that the judges were tossing all the tickets during trial.  Rationale was inability to confront the accuser in court.  This will work out the same way.  

The other little game played by red light camera cities is to shorten the yellow light times so as to issue more tickets.  Chicago is among cities doing this.  

The most important piece of technology to control red light running is the crosswalk light countdown.  This tells you how many seconds you have to make the intersection.  Want fewer red light runners?  Install these more widely.  Cheers -
