    The EU spends more resources hiring police to catch criminals while the US spends its resources on heavy punishment. Guess who has more crime. Builds on @ATabarrok theory that the probability of punishment is more important than the severity of punishment. https://blog.skepticallibertarian.com/2019/01/09/charts-police-vs-prisons-in-the-us-and-europe/ …pic.twitter.com/0qp7ZPnWk3

        Great paper about this recently by @ajc730 and McCrary. One challenge in measuring this turns out is that year to year police employment levels can be incorrect. https://eml.berkeley.edu/~jmccrary/chalfin_mccrary2015.pdf …

        Given how much measurement error could have affected prior studies, this is yet another example of my belief that just counting things accurately is one of the major obstacles to good research.

        ‘Bad guys’ is a childish term for fictional characters. Did you read too many comic books?

        Indeed. On a per capita basis the U.S. is comparatively under-policed (though note we have a very high rate of private security personnel). Yet, it's also a tragedy is that our over-reliance on arrests for misdemeanor offenses sends our jailing rates through the roof.pic.twitter.com/raDainsVGu

        Side note on the marginal crime reduction benefits of "likelihood of getting caught": we don't pay enough attention to the *perception* of risk, as this is the likely mechanism of influence. (1/2)

        Think causation v correlation point might apply here. Plus gun related & drug enforcement/criminalisation issues may factor in somewhat significantly...

        clearly this isnt proof of why crime is higher in the US, but the broader point is should resources go to increasing punishment or increasing % of getting caught.
