Even if he hadn't done anything wrong (which he didn't), when something like that happens the tendency is to think the worst of yourself. It's a byproduct of primordial guilt. Who knows, maybe the driver was Jewish, maybe Catholic. I'm guessing that he'll be looking in his mailbox for a traffic summons in the next 10 days to two weeks.
On balance, my ill-conceived photo wasn't what I wanted, but I was still compensated. For one moment, I had the force of traffic-camera intimidation in my hands.
