I from time to time look how different countries solve the same problem in different ways. Its fun to find one where an 'impossible' problem is solved in a simple rigorous way. The most shocking part is that there seems to be a complete lack of copying stuff that works even from a country next door. The preference is for every nation by it self to spend finite resources (time/money) to solve problems that have been solved elswhere. For laughs I suggest that the US police is probably doing a few things better than everyone else. We have lots of countries, each with their own formula that should serve as real world experiments. Say, do all 200 countries put the fines directly into the police budget? Or say: What are ALL the qualities one can design for in a police department or in recruitment? Then ask: How should they be prioritized? How is everyone doing this?
