2. What if you enter on yellow, and the light turns red while you are in the intersection?
After a friend ran a yellow (as in #1) and got pulled over while I was a front seat passenger, I went out and collected some video evidence of a racket being run by local cops. They're pulling people over left and right for running yellows as described in #1 and #2.
3. I'm bringing my evidence and making a sworn statement at my friend's hearing. What else can I do to bring these pigs down?
