Ah yes - the infamous "rolling stop". Lots of people do that on icy
surfaces where you don't really have much choice.

Exactly. Fairness is much more an issue with the
right-turn violation than it is with simple red light
running. In the latter, the camera doesn't lie: the
first picture shows your vehicle entering the intersection
when the traffic signal is already red. No point in fighting
that.

With a right-turn violation, the pictures are ambiguous.
In my wife's citation the first of three pictures shows
her brake lights on, and she's behind the white line
at the intersection. There's no indication of what her
minimum speed was. The clock values of each image are
shown, but that's not enough to reveal what actually
happened. Did she slow down to 5 mph...or 0.01 mph? Plug in
an appropriate value for subsequent acceleration, and
you can explain her position two seconds later in the
final image under either scenario.

HA! All that will get them is a second ticket to pay in more cases than
not. Plus the RLC camera's seem to get out of wack and then repaired
fairly frequently. I've noticed their behavior change over time.

I'd like to see those pictures.

Every RLC pic I have seen indicates a speed.

I don't know, I'd sure like to see those pictures.

It is arguable that if you have pics, and want an honest opinion
instead of the blathering of those who haven't the brains to ask for
them, so they might evaluate the evidence, you post the pics.

Such as...?

You can explain it. I'll subtract 2 seconds for the "stop".

Done:

In the first pic, she isn't past the white line.
Why did the camera trigger at that time?
