Libertarian vs. North Texas Cop

I'm still trying to figure out what agency this is. It looks kind of like a DPS Trooper from the uniform (you can see it after the 10:00 mark) and the computer terminal, but that beat up cowboy hat isn't standard trooper wear. The guy in the car is "Pastor Steve Anderson."
Stopped for running 72 in a 70. And then it turns into an inquiry about WMDs. And then it turns into a political discussion instead of a traffic stop.
