Locally, a Judge in the Warren OH area has forced the Girard City Council to remove a speed camera - State Law apparently requires a live Police Officer to issue citations.
I don't know if it still applies, but in PA the owner of the vehicle was the presumed driver in situations like this, but had the right to rat out his kids or whatever.
IAC, I object to the things because the folks providing the cameras get a cut, and are therefore provided with an incentive to set the trigger point lower than common sense might allow. Not to mention "conditions", which a human might note, but the defendant may not be able to prove.
Essentially, driving too slow or too fast with respect to the general flow of traffic, weather, or road conditions, can be a violation regardless of the speed limit. Note the "too slow" thing....
I especially object to the red light cameras. Pretty much the same thing - the camera providers
have already shown a tendency to set the devices improperly, and sometimes you have to go through the light for your own safety, or that of others. An LEO is likely to be a little more friendly about it.... Not to mention the clowns who stop short or speed up to avoid the camera's interest....
('Course, there was this idiot on a motorcycle who passed about four cars in line at a red light and drove right through it. He did slow down to check, but.... That's when you want a "red light machine gun"....
)
