Barrett may be the exception to the rule, but we would be deceiving ourselves were we to conclude that there aren't more than a few cops out there like him.
A number of years ago, I overheard a New York City police officer who was retiring for reasons of health being asked the question, "What is the biggest regret of your career?" His answer:
"My biggest regret is that I never killed a ni**er."
He was actually in a public place when he uttered those words. I am thankful that he's not on the force anymore, too.
