The state likely cannot be sued because of the 11th Amendment, but local governments may be liable under certain circumstances.
I don’t care for these rackets either.
Here in TX they try to enforce the red light tickets like any other ticket in some areas.
I can beat them in court but it’s a pain.
I assume that any citation is in the name of the registered owner. How does the court prove that the person driving the car is that person? After all, it’s the driver that committed the infraction and the cameras can’t make an identification.
