Only in the US
re: Henry Wertz, TimePilot84 - same thing happened to me when I was 17. Drove through a yellow light, got pulled over for running a red. I knew that intersection, and looked up the state laws. (In Michigan, a traffic light is yellow for 1 second per 10mph speed limit.) Had the officer's testimony of his estimate of my car's distance from the intersection when the light turned yellow, had his estimate of my car's speed. (He did not ever imply I was driving an unsafe speed or anywhere over the limit.) I had photos of the intersection. I used a whiteboard in the courtroom and ran the numbers to show that by the time the light had changed from yellow to red, my car was at least 100 feet beyond the intersection. The judge said "I don't doubt your math young man, but the officer said you ran a red." Case closed, I lost, had to pay additional court fees.
In US courts facts don't mean shit, The Law is not the same as Justice.
