My point was the carelessness with which Vaughan constructs his arguments. That whole letter is riddled with deeply flawed arguments: did crime go up in Atlantic City because of the casinos or because crime was going up everywhere in cities like that at that time? Did the bars and restaurants near the casino close because of the casino or because a casino isn't a panacea for an otherwise dying neighbourhood? He keeps referring to deeply troubled cities like St. Louis and Atlantic City, but doesn't talk much about places like London, Paris, and Melbourne, which seem to be doing just fine with casinos.
Uh...
