Arizona Republic:  “Photo-enforcement cameras may not last through the summer on Arizona’s highways, given recent activity at the state Capitol to shut down the program.  Pressure is growing among state politicians to scrap the network of freeway boxes that snap photos of speeding motorists, and a few lawmakers have introduced bills that would fundamentally alter the system or do away with it altogether.  Gov. Jan Brewer is leaning toward letting voters decide whether to keep the cameras.”
