Once you've been pulled over, a police officer is unlikely to change their course of action based on anything you say to them. Especially in this case, of not coming quite to a full stop at a red light before turning right. The cop knows it was safe to do so. They just want the ticket revenue or to fill up their quota for the month. Or they're just having a bad day and want to harass someone who can't fight back. Or, if I'm being charitable, they're an incessant rule-follower who doesn't understand how reality works.
