Some important details left out of this article: there is not a shred of evidence that the cop was perpetrating any racist act, including profiling, that allegedly provoked Gates' angry response. Gates' version of what took place inside the house doesn't square with the cop's excellent background or explain the cop's motivation for alleged racial profiling. What we do know is what took place outside the house, to wit, Gates' loud and vociferous racial accusations about the cop in front of a public audience. It seems to me that the cop took offense at the embarrassing personal nature of the racial accusations. I don't know how many of us civilians, much less cops, would have been able to walk away from Gates' diatribe which the cop evidently regarded as hugely unfair. Advising the cop to walk away is easy. If the cop saw walking away as granting Gates an unfair victory, how would this then impact on the reputations of the cop and the Cambridge Police Department?
