But at the same time, we need to be aware of its limitations and be honest in terms of its performance."

Los Angeles In its first 21 months, Chicago New York City First instituted predictive From 2015-2017, Chicago saw a surge in gun violence, policing in 1994 bringing media attention to the city's use of predictive policing In a 2017 investigation, the New York Times found that PredPol resulted in 2X the arrests as professional criminal analysts – Suggesting to a greater reduction in crime. But a few years later, property times were back up By 2003, murders the lowest since 1964 BUT, the same decrease in violent crime was seen across the country - including regions were predictive models weren't in use Nationwide Violent crime is falling, but the public hasn't noticed 1/4 to 1/3 of the highest risk individuals were involved in a violent incident in 2016 Less than 20% of the city's total gun violence involved high risk individuals From 1993-2018, the majority of Americans believed that crime increased nearly every year Roughly ½ of Americans are Over the same period, Violent crime fell by Property crime fell by listed in facial databases 51-71% 54-69% 00 accessible to the F8I MULTIPLY The Problem: Al's Data Feedback Loop Al's Flaws Marginalize Minorities African Americans are more likely to be included in facial recognition databases due to over-policing of black communities Facial recognition algorithms* are more likely to misidentify Asians, African Americans, and Native Americans *developed in the United States In a test of Amazon's facial recognition software, 28 members of Congress were falsely identified as criminals John Isakson Edward Markey Pat Roberts Sanford Bishop George Butterfield (D-Georgia) Lacy Clay (D-Missouri Mark DeSaulnier Adriano Espaillat Ruben Gallego Thomas Garrett Greg Gianforte (D-Arizona) (R-Georgia) (D-Massachusetts) (R-Kansas) (D-North Carolina) D-California) (D-New York) (R-Virginia) (R-Montana Jimmy Gomez (D-Califomia) Raúl Grijalva Steve Knight Luis Gutiérrez (D-Ilinois) Leonard Lance (R-New Jersey) John Lewis (D-Georgia) Frank LoBiondo David Loebsack David McKinley John Moolenaar (R-New Jersey) Tom Reed (R-New York) (D-Arizona) (R-Califomia) (D-lowa) (R-West Virginia) (R-Michigan) 20% of members of Congress are people of color 39% o of false matches were people of color Marc Veasey Norma Torres (D-California) Brad Wenstrup Steve Womack Bobby Rush (D-Illinois) Lee Zeldin (D-Texas) (R-Ohio) (R-Arkansas) (R-New York) When Al Is Trained On Historical Crime Data Existing bias becomes a core component in its predictive algorithms Predictions may become self-fulling, Results and enforcement as police ramp up enforcement in communities the ignore crimes that go unreported software labels as "bad" Why? According to the Bureau of Justice Statistics, People are less likely to report crimes they think will go unsolved Only 43% 34% "There's a real danger, with any kind of data-driven policing, to forget that there are human beings on both sides of the equation."
