Should black gang rapists be arrested?

In 2010, an 11-year-old Cleveland, Texas, girl was repeatedly raped by as many as 20 men and boys. The crimes became known because one of the idiots video-recorded one of the assaults, and one of the little girl's classmates saw it and told a teacher. 

So, there is no doubt the assaults occurred and no doubt about who did it. Yet the newspaper reports that the case was complicated by "a belief among many in the predominantly black neighborhood where several of the suspects live that the arrests were racially motivated. All of the suspects are black, while the girl is Hispanic."

I guess I don't understand the complaint. Are they saying that black men should be allowed to rape little Hispanic girls?
