Guiliani's crackdown on crime coincideded with a nationwide drop in crime in the 1990s, in cities that didn't implement the same tough "broken window" policies as NYC. Between 1991 and 2000, homicide rates fell from 9.8 to about 5.5 per 100k people, which is a drop of 44%. There were probably multiple overlapping causes [1], but the most compelling explanation so far is the removal of lead from gasoline in the 1970/80s [2].
