This article has interesting implications for the current attempts to revive community policing, which promotes the idea of police getting more involved and integrated into the communities in which they work, with the hope that they become more trusted and aware of the social landscape in which they are operating.

By integrating themselves with the community, they would necessarily fall under the influences of some of the community's norms, and perhaps be better tuned, and also more accountable, to it's norms of righteousness.

That may work in many cases, but the article seems to assume that most individuals in any community will promote righteousness in the community's interest.

What happens if the community lacks the social norms to enforce righteousness, especially with respect to the property rights and justification of violence? What happens when the "community" is hardly a community at all, but, due to its socioeconomic circumstances, is a place where suspicions of neighbors and incentives to cheat the community are pervasive?

Whose job is it to establish the norms of righteousness where they are lacking, or significantly degraded?
