| I find it very malicious to just drop numbers like this. It gives the impression that you state a simple fact, while the reality is much more complicated than that.
The studies on the subject require much more subtlety and statistical understanding when interpreting the results that a 2 line quotation to make a point. There are a number of factors to take into account when giving credit to such studies: - Is there enough observations to have statistically significant results? (i.e. do we have enough occurences of police strikes to really have meaningful results? can we have overwelmingly influencing factors not present in the studied samples: I guess it would likely highly depend on the city where the strike happens also) - Did the sample properly allowed the isolation of the variable being studied against other influencing factors? - What is the collinearity between the variables used for the regression? (i.e. if violence complaints are made on the spot, then less police means harder to fill complaints, it doesn't necessarily mean less violence) "Freakonomics: A Rogue Economist Explores the Hidden Side of Everything" has a good introduction to the challenges of such studies, and discusses a bit the particular case of police. |
