Advances in PredPol

Published on 17 December 2023.

Introduction:

In a recent development, Sound Thinking, the company behind the controversial ShotSpotter technology, is acquiring Geolitica, the creator of PredPol, a predictive policing tool known for exacerbating inequalities. This consolidation raises serious concerns about the potential harm these technologies may inflict on communities. Here’s why cities should act swiftly to ban predictive policing and discontinue the use of ShotSpotter.

Predictive Policing Advances:

Duncan Purves and Ryan Jenkins, philosophy professors from the University of Florida and California Polytechnic State University, respectively, have unveiled a groundbreaking ethical framework for place-based algorithmic patrol management. This method involves the analysis of past crime data to predict areas with an elevated likelihood of criminal activity. The voluntary framework, developed over a four-year period, consists of 63 recommendations targeting developers, police departments, and community advocates.

A distinctive feature of the framework is its emphasis on community involvement. CASMI’s workshop, “Best Practices in Data-Driven Policing,” brought together a diverse group of stakeholders, including software developers, computer scientists, law enforcement, lawyers, and community advocacy groups. According to Kristian Hammond, director of CASMI, the goal is not just to bring stakeholders to the table but to empower and listen to them. The recommendations prioritize seeking input from community advocates, recognizing their concerns, and ensuring their voices are heard.

The Problem with ShotSpotter and Predictive Policing

Background:

ShotSpotter, an acoustic gunshot detection technology linked to over 100 law enforcement agencies, has been found to be inaccurate. False alerts have led to the deployment of armed police in situations where no armed resistance exists, putting innocent residents at risk. The acquisition of Hunchlab in 2018 further integrates predictive policing, allowing real-time updates to patrol missions. The flawed nature of ShotSpotter raises questions about the reliability of its data and the potential for misuse.

PredPol’s False Promises:

PredPol claims to predict crime using algorithms, a notion debunked by studies. Despite its inaccuracies, the predictive policing industry is projected to be worth over $5 billion by the end of 2023. Predictive policing perpetuates existing inequalities, concentrating law enforcement efforts in specific neighborhoods and leading to further victimization of marginalized communities, particularly people of color.

A Merger: Cause for Concern:

 The acquisition of Geolitica by Sound Thinking signals a consolidation of harmful technologies. When companies merge and bundle their products, cities may unintentionally deploy a suite of flawed technologies without adequate oversight. This lack of transparency and control poses risks to the public and undermines the role of elected officials.

Looking Ahead

Skepticism about the efficacy and ethics of these technologies is on the rise. Some cities and the EU have already banned predictive policing, while federal officials express concerns about its dangers. The U.S. Justice Department has been asked to investigate the disproportionate deployment of these technologies in majority-minority neighborhoods. Additionally, major customers of ShotSpotter have canceled contracts, reflecting a shift in public opinion.

Researchers are actively engaging with a major developer of data-driven police technologies to test the framework’s recommendations. The aspiration is to contribute to positive outcomes for public safety and police-community relations, moving towards a more harmonious future. As the ethical landscape of data-driven policing evolves, this framework stands as a significant step in fostering responsible development and deployment of technology for the benefit of all.

As companies consolidate, it becomes crucial to organize and resist the deployment of these technologies. The merging of Sound Thinking and Geolitica underscores the need for cities to act swiftly. The call is clear: ban predictive policing and cease the use of dangerous, inaccurate gunshot detection technology.
