Thought I heard the cop tell the guy that "I've been doing this for 20 years". Seems in 20 years he would have learned some tact.
Or been super fed up with azzhats by then. Nevertheless, THAT is not allowed to affect the job a LEO does. The great majority that I see are VERY polite, not matter how much grief they get from the azzhat/moron. Those that can't should be fired. I know that I couldn't do it... I have a very low tolerance for azzhattiness.
