His style was authoritarian, but there is one problem that he fixed that I thought could not be: the homeless. When I moved to NY in the early 80s, the streets and subways teemed with homeless, the likes of which you only thought possible in Calcutta. Guys trying to 'wash' your windshield when you stopped at a light. Within about 3 years they were all gone. Where they went I have no idea but I don't care.
