Under De Blasio, homicides ranged from 289 to 328 his first six years, the lowest homicide numbers since the 1950s when the city’s population was much lower. In this, his seventh year, the numbers project to about 386. Basically we aren’t even headed back to Bloomberg days.
NYC is anything but out of control.
