The worst affected cities have the widest safety nets. These kinds of crimes are fairly low in towns in Mississippi ravaged by worse poverty and with their own (painkillers) drug problems.
The nature of the drugs (fentanyl), the manifestation (homelessness) and the enforcement (or lack there of) are central to the problem faced here.
It is not a US problem. It is not a west problem. It is not a city problem. It is an urban-west-coast-city problem.
