"neighborhoods" died for the most part....before families grew in the same neighborhoods and everyone kinda looked out for one another and some disciplined other people's kids "take a village to raise a child" comes to mind..
but now people move around a lot more ...more transplants, development of neighborhoods, kids going off to college is more common most never come back to their city/hood to live, ...so many factors now neighbors hardly know each other ....couple that with the new social wave of "mind your business" or "it aint our problem" that's like a ton of influences, lessons, and experiences that kids now a days are missing out on....
"neighborhoods are now hoods cause nobody's neighbors"-de la soul 'stakes are high'
I remembered this video on SOHH that discussed how the level of trust in our society is crumbling and to the point where isolation is actually the solution to many people's problems.
To reach out to these kids, you gotta shame them for their bad behavior. Compare their behavior to the likes of the KKK and corrupt cops and Pac n Biggie's killers. Once you make that comparison clear as day, kids will be shamed into doing the right thing. Break them down to build them back up.
