The Post, which enthusiastically championed the NYPD during this year's turmoil, portrayed this slowdown in near-apocalyptic terms—an early headline for the article above even read "Crime wave engulfs New York following execution of cops." But the police union's phrasing—officers shouldn't make arrests "unless absolutely necessary"—begs the question: How many unnecessary arrests was the NYPD making before now?
Policing quality doesn't necessarily increase with policing quantity, as New York's experience with stop-and-frisk demonstrated. Former Mayor Michael Bloomberg asserted that the controversial tactic of warrantless street searches "keeps New York City safe." De Blasio ended the program soon after succeeding him, citing its discriminatory impact on black and Hispanic residents. Stop-and-frisk incidents plunged from 685,724 stops in 2011 to just 38,456 in the first three-quarters of 2014 as a result. If stop-and-frisk had caused the ongoing decline in New York's crime rate, its near-absence would logically halt or even reverse that trend. But the city seems to be doing just fine without it: Crime rates are currently at two-decade lows, with homicide down 7 percent and robberies down 14 percent since 2013.
