Cayabird, I think you only care about this rape because it was committed by an illegal. Which is a shame. Most rapes are committed by people born in the US. Are you 30? Then  you know women who have been raped; maybe a man too. I know a number of women who have been raped. And a man. None of them were raped by an illegal.

It's a very common crime. There's someone being raped as you read this.

There is no "bias by omission." The rape you mention of a young woman in Maryland isn't "notable" enough to make most national news stories. There are hundreds, thousands of women (and men) raped each day in the US. The nat. news only picks up on those that have something that would take the story beyond the local level (a famous person involved, particularly gruesome, etc). If the news covered every violent crime in the US, there'd  be no room left for other news.
