There has been a great deal of topic drift here, but a few comments on this story:
It is unfortunate that a great percentage of people in the United States, including black people, are more fearful and/or distrustful of black people than they are of other kinds of people. What is perhaps more unfortunate, however, is the corollary that such an opinion springs mostly from the very poor condition of African American culture.
It is statistically true that black people have, since the Civil War era, been responsible for a disproportionate amount of violent crime, and thus a certain level of fear of them (particularly young black men) is entirely warranted, and not, in my view, racist. Moreover, to the extent individual black people choose to adopt styles of dress and behavior that are cartoonish, profane and/or celebrate a criminal culture, I can't call it racism when people fear them.
My own view is that there are a number of issues at play here, in terms of how we got to such a deplorable situation. A great percentage of the blame, modernly, lies with the existence of post-Johnson welfare state policies that make it possible to eke out a modest, humiliating living without working. Another chunk of the blame lies with the War on Drugs, which has devastated many black families, without any legitimate justification IMO.
Perhaps the most important cause (which is affected by both of the above) is the depressingly widespread abandonment of families by black men. If the same guy fathers 10 kids with 8 different women, and takes care of none of them, he has just created a whole web of problems. At this point 66% of all black kids are in single parent households, as compared to only 24% of white kids -
http://datacenter.kidscount.org/data/acrossstates/Rankings.aspx?ind=107 If we could bring that number down to 24%, substantially all the rest of this would take care of itself, because kids raised by two parents are much likelier to have discipline, to take school seriously, and to be able to build a life financed by something other than public assistance and/or crime.
As for the other comments in this thread, I do not agree, necessarily, that white people are the "least racist" - that has certainly not been my perception. Moreover, I think the prevalence of black-on-white crime relative to white-on-black crime is in no way illustrative of racism by the perpetrators - just indicative of the relative prevalence of criminal behavior by black people versus white people. The victims of most violent crimes perpetrated by black people are themselves black - are we supposed to consider those hate crimes as well?
In general I think we are moving in a positive direction with respect to racial relations, and I would love to see African Americans as a whole deal with the problems that have made them into a persistent underclass (crime, abandonment of families, de-emphasis on education, over-reliance on public assistance). I know these are huge issues but acknowledging them is the first step toward fixing them. I expect that if and when they are able to do so, people as a whole will be far less prejudiced toward them.
