Stop and Frisk Term Analysis

“Stop and frisk” is a New York City Police Department practice of stopping, detaining, questioning, and frisking or searching civilians on the street—especially in low-income, high-crime neighborhoods. In the early 2010s, the NYPD reported stopping and frisking over 684,000 New Yorkers in one year. Nine out of ten people subjected to stop and frisk during that time period were found innocent—and 87 percent of those targeted were Black or Latinx.

These types of low-level crimes populate their models with more and more dots, and the models send the cops back to the same neighborhood.

This creates a pernicious feedback loop. The policing itself spawns new data, which justifies more policing. And our prisons fill up with hundreds of thousands of people found guilty of victimless crimes. Most of them come from impoverished neighborhoods, and most are black or Hispanic. So even if a model is color blind, the result of it is anything but. In our largely segregated cities, geography is a highly effective proxy for race.
