A maskless Tennessee State Trooper went on a major power trip, going face-to-face with a man not accused of any crime … before allegedly tearing away the man’s face covering.

Andrew Golden says this went down Monday near the Tennessee State Capitol building as he was recording state troopers who had pulled over a motorist. He says he kept a safe distance away on a public sidewalk before State Trooper Harvey Briggs — who was not involved in the traffic stop — threw a fit.

Check out the video … Briggs, who again is NOT wearing a mask, warns Golden about cursing in front of him. Golden, who kept recording, asked Briggs “why his hand is on his gun” … and the cop said, “Because that’s the way it always is.”

Golden claims Briggs then stepped on his foot — all without wearing a mask, mind you — and then, suddenly, ripped Golden’s mask off his face. He immediately called out Briggs for it … and you hear Briggs deny it as he walked away saying, “I’m tired of you people making stuff up.”

Tennessee’s Dept. of Safety and Homeland Security tells us it’s “in the process of reviewing the matter.”
