Not anymore. I worked in communications for a nonprofit that had programs for foster youth so I used to interview them and I had some other interactions here and there. Not gangbangers or anything, just kids with really rough lives. They know right from wrong like anybody else but they tend to have a lot of trauma and self regulation issues and just do so much ridiculously stupid stuff that messes up their lives as a result. I don't know the answer here, but community mediators has generally been the most successful at reducing violence but it's hard to scale and easy to cut when the budget is tight. It also works best when the police make an effort to keep the same cops on the same beats and building relationships, but we know how hard that is.
