I had a buddy in SanDiego that said everyone in his office all had gotten the same photo red light ticket and it was a right of passage thing to have your picture blown up and hanging on the cubicle wall. Turns out, the maker of the photo light camera had some tie in with the city, or kickback er some such other conflict of interest. The yellow lights were on a shortened cycle, thus giving the city a lot more citations that were not really legit. I guess the scam eventually got broken up but it shows hows these types of things can easily be abused. Who knows how much money they made off innocent drivers before someone figured it out.
