My dad had a problem with a cop like that.
My dad didn't come to a complete stop at a stop sign (nobody there but him) and a cop pulled him over and my dad was upset so he wasn't looking at him, and out of nowhere the cop tells him "You best look at me boy" also, coming from somebody like 10 years younger then you, thats kinda aggravating, so my father refused.
He was taken in, no charges were kept on him.
