Increase in homicides. What is root cause?

An increase in homicides in Chicago from 2011 to 2012 was the focus of a feature in today's Chicago Tribune. I've written about such stories often in the past, in an effort to mobilize more support for the growth of volunteer-based tutor/mentor programs in high poverty neighborhoods.

However, every time I read of a shooting, I wonder how connecting a mentor in the life of kids in that neighborhood can have a direct impact on the current level of violence.
It causes me to ask, "what is the root cause" of this violence?

So I've begin to look for web sites which talk about "root cause analysis". I've listed a few below. I encourage you to add your own.

In my search for concept maps I learned about this link where you can search the C-Map library for maps that have been created.

I'll add a link to this blog article in the library I've been creating. Each of these nodes points to web sites with in-depth information that people can learn from, building their own understanding of the root causes of poverty and urban violence, along with possible long-term solutions.
