There are many,many,many,*many* bad and dangerous people in this country...most of them males.Cops,not being mind readers,can never be sure if a particular individual is gonna attack them.
As a result it's always good a idea when interacting with a cop to not resist,not to mouth off,not to make gestures or say things that could be interpreted as threatening.This is doubly true for guys.
In the three police encounters I've had in my 70 years (yes,I've led a *dull* life) I've followed those very rules and,as a result,the worst thing that ever came from these three encounters was one ticket for $100 (which I fought in court and won).
Just wondering - did you watch the video?
