There is nothing better than to be connected with your community. Being connected with your community is the way forward to a better community, unless everyone in the community collectively does not want it to improve through various behaviors. A strong community has members looking out for each other, and removing any outsider they see fit.
While this is usually seen as a positive thing, it can often be negative when an outsider tries to intervene in the community. This also includes cops, where the community members will refuse to cooperate, and instead try to handle their own business. This is not just limited to urban communities like hoods, but also in a wide variety of communities and even organizations.
