Over and over again we've seen cases where cities clearly put in red light cameras not for safety purposes (despite that being the "official" reason), but to increase revenue. For example, many cities have been caught decreasing
the time of the yellow light before it turns red -- a move that definitely increases accidents and puts people at risk, against the law. However, since it increases the number of cars that run red lights, it means more revenue. If this all seems very corrupt, it appears that in at least some places, that corruption might be explicit. Reader Murdock points us to the news that 38 public officials in Italy may face charges
for accepting kickbacks and bribes in association with a redlight camera company, to install such cameras, decrease the timing on yellow lights, and then collect money. Oh, and it worked. Lots of money was made, but it's not clear that anyone was any safer.
