No argument was made. Observation: it was directly relevant. Observation: it possessed the standard discussion level of linked or formal support you demand of your own claims, namely none. Make of these observations what you will. In addition, it was accurate: cocaine abuse on Wall Street did peak and slide, in a manner made famous in American culture in various movies, books, etc., in syncopated approximate synchrony with nearby "troubled" neighborhoods. https://clinicalservicesri.com/cocaine-abuse/where-it-comes-from/ http://nymag.com/news/intelligencer/modafinil-2013-4/ https://brobible.com/life/article/nyc-investment-bankers-divorce/ https://www.mediaite.com/tv/forget-...kudlow-is-one-of-tvs-worst-financial-pundits/ And it managed this familiar roller-coaster boom and bust chronology, common to many such things, without the mediation of the police. Meanwhile, the lack of necessary correlation, dubious mechanism, and exhibition of features of standard interpretative error common in the field, count heavily against any conclusions of causality or assessment of function regarding extra police. It is at least as likely as not that the extra policing was in practice another of the troubles faced by the "troubled neighborhoods", one of the worst ones even - and one that Wall Street was spared, for some reason. An interesting illustration of which kinds of bad stuff receive material help, and which are left to thoughts and prayers for their remedy.
