Violence in Poor and Black Communities

A headline from the Washington Times says, "Chicago concealed carry gun permit law 'disarms' poor, blacks". The implication is that the poor and blacks are being discriminated against. The discrimination is presumably based upon unavailability of firearms to them because of limitation of the concealed carry gun permit law. Nothing could be farther from the truth, when you look at the total picture.
The article goes on to say that in ZIP code area 60624 there have been more homicides, robberies, assaults, thefts and narcotics charges combined than any other ZIP code in Cook County, IL, when measured on a per capita basis. Its population is 98 percent black and averages a median income just above the poverty line. A separate video says that the violence is caused by the populace being deprived of concealed carry gun permits, which cost on average $650.
By comparison, ZIP code area 60464  boasts a negligible crime rate: Only one homicide has been committed in 10 years, according to the most recent state police data. Ninety-six percent of its residents are white, earning an average income of $121,000..
The intended message is that the poor and presumably some blacks are unable to protect themselves, because they can't afford to pay for a concealed carry gun permit. Hogwash!
In the ZIP Code area with the highest crime rate, the atrocities are mostly committed with guns. In other words, the residents are robbing and killing each other with firearms, which are readily available to them and having nothing to do with the concealed carry gun law. Since the residents have these guns illegally, and presumably are concealing them illegally, they start out by being lawbreakers. It is clear that they have no respect for the law and use violence as their way of life.
Contrarily in the high income ZIP Code area, the residents respect the law by legally obtaining firearms and permits for concealed carry. It is highly likely that without a concealed carry gun law, the criminal statistics would still be approximately the same. The low income people would continue to kill and rob each other at gunpoint, while the more wealthy would continue to have lower rates of crime, because they are believers and adhere to the concept of law and order
I'm not sure what we can do about reducing violence in the low income and black communities. Violence there seems to be. A cultural matter difficult to change. Police have been putting perpetrators in jail, but the jails are so full that this is not an obvious solution. The net result has been to reduce the jailing and let the violence continue to take its course.
Is a violent way of life too culturally ingrained to be changed? Education may be a possible solution, but the educational system has its own set of problems, with the likelihood of being unable to deal with this one.
