I figure its just a moment in life, and no need to go instantly crazy, or talk yourself into some very expensive trouble.
Since you didn't think the Cop or LEO was going to walk up and blow your head off, you didn't shoot him with your licensed handgun did ya? So, relax. Turn on your car's inside light, keep smiling, and everything will be fine shortly. doing that- It always works out that way.
From the Police Officer's perspective: Look at the possibilities-
It might have been a young Cop who has had very little experiance with 'good citizens' or us 'old folks' who aren't afraid/intimidated just by being in thier presence.
Put yourself in his place:
Out wherever you were, and ya pulled over a car, not knowing who or what was inside,,,,,, How would you react and handle that situation? Would you be over cautious like he did?
Or, would you have known at a earlier stage of the game that you--- perhaps like he himself will realize in a few years or months---that he just shouldn't be a Cop in the first place?
I figure as long as you didn't get shot or have to shoot anyone else--- its all OK, and negotiable in the long run.

Then again,,,, here's a example for ya:
My Grandfather was a 'Career Cop' his whole life in the Deep South. From the mid-30's until he passed away in 1975. He'd been a City Cop, a Sheriffs Duputy, a Marshal, a Police Chief, pretty much everything but a Mississippi State Trooper.
One day around 1968 or 1969, probably at age 60 or so, after 30-something years as being a Cop, and never haveing aimed his weapon at another person,,,, he pulled over a car that ran a "Yield" sign, in his little one traffic lite, whistle stop town.
I didn't think it was possible to run a Yield sign, but I guess it is- or was back then if you were a stranger with out of state license plates.
Here's this 60 or so year old Cop, and what popped out of the car he pulled over was a guy on the FBI's 10 most wanted list........ who promtply went (unhurt) to his jail, and waited for transportation/escort---- 'up North'-- as he called everything above, and East of Jackson, Miss.

Roll that around in your head awhile.
I don't think there is a moral to this story, but like your's, its good food for thought.
