Ok, maybe I'm a tad biased. Was living round Arthur at the time, and folks didn't like him. Social Clubs were all over, was part of the life. He targeted them, pissed people off. Neighborhood was changing anyways. Now more of them are Albanian or Yugoslavian.
Also, someone I'm related to liked him because the Mafia forced him to pay for their sanitation co services for his office. Rudy stopped that. So, yeah, I might not be looking at the whole picture.
