You know, I'm not sure that racism is the underlying problem in the story. The point being made was that the child was completely uncontrollable...the fact that the police had already said that they'd handcuff her before (whether serious or not) does give the idea that this was not a single outburst, nor an overreaction.
The fact that Ja'eisha is black isn't relevant, unless you're implying that they wouldn't have called the police in a similar situation if she was white (I think they would have done...), or unless someone is implying that Ja'eisha was violent and uncontrollable because she is black. No-one was, and anyone who is must be a bigoted fool.
That her parents clearly have a major problem on their hands, and that they are likely to shoulder a good part of the blame for her standards of behaviour - yes. That they're black? Irrelevant.
Racism, though, is a very easy charge to level, and a very difficult one to refute. I can't speak for American society, but British society is having resurgences of racism because of the rather large and sudden number of immigrants into the country. However, most racism here isn't open - its the insidious (or natural?) sort which leads you to identify more closely with people who are like yourself. Pacifists do not seek out warmongerers, scientists and artists have little in common, everyone hates lawyers...
Judging someone by skin colour is only at best a value judgement on what else that says about them, like what clothes they wear, or how they hold themselves, and an inaccurate one at that, but its one you can't stop people making, at least not yet.
Racism here is not terrible, but then we have a very different racial history to America.
