I'm so sorry. This injustice is just horrible.
Jessica, maybe check if your state has a law about yellow lights. In my state, Oregon, the law is rather unique and I know most states don't have this law, but check if your state does. If not, then maybe petition for it to become a law?
In Oregon, the yellow light requires all vehicles to stop if it is safely possible to do so. (part of Oregon law ORS 811.265). This law allows for criminal charges on running a red light because then the person has run not only the yellow, but the red, which is reckless endangerment at the very least. I do have to say I don't think this law has made much difference in the Portland Metro area. The red-light runners are just horrible. But if your state does have this law, then maybe it's worth reminding the justice system of it.
