> repeated prisoner's dilemma games I think this is why it is very important with communities: so that your interactions with other people are mostly with the same people instead of mostly strangers. The other important aspect is that people thinks "we have the same values, so we are the same team", as you will otherwise always select to deflect due to mistrust of the other part. Police on its own is not enough, they cannot solve most crimes without help from citizens. A police officier without good informers is not good police ("The Wire", see IMDB). So police is only really effective in a high trust, pro-socal relationships society.
