That is no more personal than you suggesting I'm insulting cops. Either limit yourself to addressing the points I'm making (rather than forming opinions about any effect they might have on others) or get a thicker skin.
"My review of the tape indicates he remained calm and levelheaded throughout."
W.C. Fields was a master at being calm, levelheaded and insulting. You're having me believe one precludes the other.
"First, I fail to see where Mr. Darrow "mouthed off" to the cop."
What can I say? That's not my fault.
"Evidently you do believe the cop has to stand there and take it, or you wouldn't claim he should be fired"
Not at all. Unlike you, I said I would expect a cop to react if I acted like a smart a$$. Sure, this cop overreacted but the kid wasn't hurt or arrested on trumped up charges. His ego got bruised.
But, since the cop's overreaction was caught on tape, he left his superiors no choice but to fire him.
Ah, but there's the distinction. I only expect bad cops to react if someone acted like a smart a$$; you evidently expect all cops to react. A case of projection, I suspect. Just because you're unable to restrain yourself, don't assume everyone else lacks that ability.
