The Tennessee cop who threatened a man who was shooting video of a police stop and then ripped the guy’s face mask off has been fired.

Trooper Harvey Briggs got his walking papers Friday … terminated for unprofessional conduct. He had been placed on leave 2 days earlier, after video surfaced of the confrontation.

Briggs, a 22-year veteran of the Tennessee Highway Patrol, went on a power trip, threatening Andrew Golden, approaching him and then ripping his mask off in a fit of anger, before walking off. Briggs seemed to be triggered after Golden used a swear word … and that’s not a reason to threaten to arrest someone or rip their mask off.

Golden was shooting the stop from a distance from a public sidewalk before Briggs went on a tear against him. Briggs filed a complaint and action was clearly and swiftly taken.
