I lived in an area that could compete for worst in my city. And it was legitametly bad. There was a gang but oddly it was a small one smooched between two larger ones territory wise and it effectively was like a little crime family as the leadership all came from one family. There were basically three types of folks. The criminal gang types, the im going to act shitty because its the ghetto assholes, and the last third where hard working and down on their luck folk who appreciated niceness and politeness. Now granted they also did not call police (which is understandable) which is why the gang could operate with somewhat impunity.
