Red Light Cameras

I think they're good but the objective should be to discourage people from running lights, not trying to gain revenue. As such, signs should be posted so that people realize that drivers may stop short as a light is yellow to avoid getting tickets. The unintended consequence of people stopping suddenly could cause accidents. Likewise, if someone is on your tail you could be put in the position of having to decide between running a light that may have JUST turned red, versus getting hit by the driver behind you.
