Earlier quoted context omitted.
There are pictures to prove the VEHICLE was there, but the mechanism then assumes the owner of the vehicle was the driver, which is a problem.
Take two pictures then maybe, one from the front, one from the back. But also, unless the vehicle was stolen, why not put the burden of proof on the owner. Don't people know who they're giving their car to? I think that's how it works in many European countries. If the car is stolen, just file a report.
In the U. S., I'm innocent until proven guilty: prove it was me. No, I'm not telling you who was driving, because my lawyer said something something 5th amendment. But that's the theory, as this not-a-lawyer understands it. In practice, you'll just pay the ticket because the future of civil rights law does not rest on determining who was driving the car that day, and you know it was you anyway.
