I believe rosebud thinks this is a story of national interest not because it is so on its own, but rather when compared to how the media reports these stories in general.
Was the Matthew Shepherd case a "story of national interest?" Probably not. Yet, the media, in its frenzy to capitalize on its propagandizing of PC sensibilities deemed it to be so, thus we were treated to wall-to-wall coverage and at least one made-for-TV movie on the case.
I hesitate to speak for rosebud, but I think he/she means that for the media to be consistent, they would treat this case with at least the same urgency.
Five people are dead. But for the grace of God it would be six. The people who did this are on trial. When convicted, and I have no doubt that then will be, and when sentenced to death, and again I have no doubt that they will be, they will be taken to the correctional facility at El Dorado and held there through their endless appeals before being bussed over to Lansing and executed. I don't care if the victims were white and the killers were black, or vice versa. The killers are going to pay and all the media attention in the world will not change that, or speed it up.
