Tikimon, wrt your extraordinary statement 'No major city is "over whelmed" by gun violence' -- every Sunday my congregation prays for the previous week's victims of gun violence in the large city next door to the east of where I live. The names of all the victims are read out and separated into wounded and killed. We pray for the repose of the souls of those killed and the recovery of those wounded.
The Sunday after the Fourth of July, 82 names were read out, fourteen of whom had been shot dead. It was a long mass.
We care about the fact that people are not safe on their streets or even in their homes. One reason we care is we don't want it all spilling over to our suburb. So we pay for a relatively large and pretty aggressive municipal police force with top of the line cars and a zero tolerance policy on graffiti, tagging, and youth curfew violation. We also pay higher insurance rates because of all the crime 'next door'.
We also pay high county taxes to be able to afford to treat the victims of gun violence, many of whom require lifetime care, colostomy bags, wheelchairs, mobility assistance, round the clock nursing care, etc. We pay for the county jails and court system, probation officers, etc., etc.
One of the reasons the county hospitals struggle to provide adequate care for those living with heart problems, diabetes and stress related disease is that there are so many of them suffering as a direct consequence of living in gang war zones where good grocery stores are loath to locate and where the everyday challenges include dodging bullets. Another reason is that it costs an incredible amount of money and takes up vast medical resources resources to treat the victims of gun violence, from ambulances to ER staff to critical care facilities to long term after care.
My late exFIL was a neurosurgeon in a smaller midwest city and spent his weekend nights in a university hospital dealing with massive head wounds and spinal injuries inflicted by AK-47s, Uzis, and other weapons that have no place in life outside of warfare. He found it depressing -- so many wasted lives, so many hours at the operating table, so many people who 'survived' due to his heroic efforts but lived their lives afterwards in skilled nursing facilities. The worst experience of his life was trying to save his own niece who had been shot in a robbery. She lived but was severely brain damaged and required round the clock care until she died nine years later. Many weekends he was on his feet operating for 18+ hours straight. Many good colleagues decided to leave and find more peaceful pastures.
The gangs drive business away and perpetuate the socio economic problems that make life in the ghetto so hard. Established businesses in parts of the nearby city that are not located in gang turf pay higher city tax rates in order to maintain the necessary policing in the war zones.
Money spent on simply holding the line on gangs, often with little success, is money that is not available for the public schools or the local county health clinics or the local mental health clinics.
Every single individual in a county where gun-inflicted violence is prevalent pays and pays and pays again. You are completely wrong to state that no city is overwhelmed by gun violence.
