I think the red light camera regulations they passed in Texas force them to follow Texas DOT regs for yellow light times and such. They also have to do some sort of traffic study for each camera. It makes it harder to put them up and harder to screw with them afterwards.
Personally, if the traffic safety of the intersection or the section of highway is so important, then it is important enough to be done by a uniformed cop in a marked car. If someone does something illegal, they should be chased down and given a ticket right then. Getting in the mail later defeats the purpose. Half the people won't even remember doing anything.
