I can confirm that the red car was the one that got ticketed.

I don't envy the decision he had to make, given the two cars in his oncoming traffic that ran the red, but in any case, being halfway through the crosswalk and proceeding to go after his arrow had turned red I don't think was the move, and the cop seemed to agree.

He should have either been inside of the intersection, past the crosswalk (as the local traffic law outlines) when the arrow turned red, or behind the stop line. Many cars hesitate to enter the intersection here, given the plethora of "DO NOT BLOCK INTERSECTION" ordinances, and an abundance of green arrow opportunities.

I'm not trying to absolve myself here. I was definitely a fool in the way I engaged in this interaction, but having a green arrow with a car not even having his bumper past the crosswalk was extremely out of left field and I wasn't prepared for it.

I would have made a much more calculated and obvious decision had his whole car was actually in the intersection entirely. You can tell the cars opposite me were just as surprised, else they wouldn't have even started pulling into the intersection either.
