Thanks....that's a great tip. I figured that my going slowly in front of him was enough for him to know I wasn't looking to evade him, but next time I'll know better. It still doesn't warrant him anger, IMHO.
There's good and bad cops. My father in law was a combination of Barney Fife and a sadist. Bad combination especially when badge is added. His gross mismanagement & his own physical abuse of prisoners in a penal farm he ran led to one of the biggest man hunts in my states history decades ago. My wife was a young girl at the time and saw a lot of prisoner abuse by him because they lived at the penal farm.
