I took over a city that had two riots in four years and I had none. And they knew they couldn't riot on me. And when I saw the people on the street in New York City, I said to myself, you're breaking Giuliani's rules. You don't take my streets. You can have my sidewalks, but you don't take my streets, because ambulances have to get through there, fire trucks have to get through there.
