The police recently had a bond issue in a local election here. The stat I saw mentioned in the debate was that 1 extra police offer was estimated to lower the crime rate by 0.1%. Based on the size of the city or whatever, they think if they added 10 cops, they think they could lower crime by 1%. IDK that seems like you're spending about a million dollars more annually to prevent a fairly small number of crimes. There are probably other things you could spend that million on that would lower crime by 1%.
