I hate to say it, though, but part of the reason this sells is it's "titillating." It's the kind of "man bites dog" story the media loves and our culture loves, too. It's an opportunity for the race-baiters and the PC-blabbermouths to cry from the roof tops about the evils of white men and so forth.
Think about how much coverage the non-rape in Duke received. Imagine the amount of coverage this story would have gotten if the races had been reversed - if it had been a young African-American couple who were kidnapped, raped, tortured and murdered by four white men.
We'd never hear the end of it.
It's no secret that America has a problem with race. That problem is not helped when the media intently focuses on race in one crime, but completely ignores it in another. There are times when race is central to a crime, but viewing all crime through the prism of race is not always appropriate.
Take this an as example: The next time a white, non-Islamic person attempts to commit an act of terrorism in the US, watch the media reaction. I guarantee you'll see much of the same type of coverage as you did with the Duke case.
