The same decrease in crime that occurred under Giuliani occurred in other cities around the country and the world which had very different policing policies. See, for example, https://pubs.aeaweb.org/doi/pdf/10.1257/089533004773563485 https://pubs.aeaweb.org/doi/pdf/10.1257/089533004773563485 Or, of course, Kevin Drum's article. TLDR: People do dispute that Giuliani's policies on crime were extremely effective.
