They had these speed cameras in Phoenix (which is pretty high on the "people would just shoot them out" scale) on the AZ-51 and people resorted to merely voting them out -- after a few high-profile incidents like this one guy who would put on a gorilla mask and intentionally get tickets while the police couldn't do anything until they actually caught them wearing the mask while speeding through a camera. Oh, and another case I remember from when the warning period just ended, this lady got tickets every day on her way to/from work until the first violation hit her mailbox, 46 speeding tickets in total IIRC.
Red light camera, OTOH, are all over the place and people don't seem to mind them as red light running (especially for left turns) is quite common.
