The black crime statistics argument points out that blacks commit crime at a way higher rate than whites and therefore blacks are more given to crime than whites – you know, because blacks are more violent, dangerous and immoral. It has been used to excuse white flight, bad policing and society the way it is – therefore helping to keep crime at much higher rates than in other rich Western countries.
For the argument to work one must assume the just world doctrine, the idea that America is more or less just and equal. Once you assume that, then you are pretty much forced to conclude there is something wrong with black people.
But for any meaningful comparison between black and white crime rates you need to take into account things like income, unemployment, the rate at which crimes are reported, etc. Further you need to assume that the police and the courts are not racist, which is rarely the case.
A good example is murder. In New York blacks are way more likely to murder someone than whites are. But does that mean blacks are more violent and savage than whites? Hardly.
I used to live in one of those parts of New York where blacks and Latinos were killing each other right and left. I never saw someone killed but I certainly heard the gunshots and knew two people who were shot dead, both black-on-black murders.
It had little to do with the supposedly violent or savage nature of black people and everything to do with the drug trade. In the process of getting drugs from South America to the good white people of North America blacks, as always, get stuck with the most dangerous and dirty work. Of course they are already breaking the law by selling drugs in the first place but blacks also have the highest rate of unemployment and so are more likely than others to turn to it. Not that that makes it right, of course, but we are talking about comparisons here.
But there is more: not only were most of the murders drug-related, the police did little about it: they seemed much more interested in protecting the lives of whites and Asians than those of blacks and Latinos. As with other city services, black ghettos are badly served by the police compared to other parts of the city.
So to just present the bare numbers,while it may seem clear-eyed, hard-headed and fair, is extremely misleading. Especially when presented to people who already have certain stereotypes about blacks. To assume from such numbers that there must be something wrong with blacks – as opposed to something profoundly wrong with how American society functions – is racist and, for white people, self-serving. It also has the effect of making crime a black thing, which means little is done about it other than to hire more police and build more prisons.
