The recent audit of New York City’s ShotSpotter system revealed that only 13 percent of the alerts generated over an eight-month period could be confirmed as gunfire. This low accuracy rate raises concerns about the effectiveness of the system. The auditors criticized the lack of transparency in the NYPD’s reporting of data on ShotSpotter accuracy, noting that the department’s accountability measures were inadequate. This calls into question the reliability of the technology and its impact on public safety.
Following the release of the audit in New York City, other cities like Champaign and Chicago decided to cancel their contracts with Flock Safety and SoundThinking, respectively. This decision underscores the growing skepticism surrounding gunshot detection systems and their ability to accurately identify gunfire. The statement from Flock Safety’s senior vice president, Josh Thomas, claiming a 90 percent accuracy rate raises doubts about the veracity of such claims and the reliability of the technology.
Professor Eric Piza’s studies on gunshot detection systems provide valuable insights into their effectiveness. While his research shows that police respond faster to shooting incidents when alerted by automated systems compared to 911 calls, there is no evidence of a reduction in gun-related crimes. This raises questions about the overall impact of gunshot detection technology on crime prevention and public safety. The discrepancy between faster response times and no decrease in gun violence victimization highlights the need for a more comprehensive evaluation of these systems.
The New York City comptroller’s recommendation to not renew the current contract with SoundThinking without a thorough performance evaluation reflects concerns about the efficacy of the technology. The NYPD’s response emphasizing public safety as a reason for contract renewal raises questions about the balance between security and accountability. Similarly, San Jose’s Digital Privacy Office’s recommendation to focus on improving accuracy with the Raven system acknowledges the potential benefits of gunshot detection technology while also highlighting the need for ongoing evaluation and refinement.
The accuracy of gunshot detection systems remains a contentious issue with significant implications for law enforcement and public safety. The findings from audits and studies point to the limitations of these technologies in reducing gun-related crimes and improving overall safety. Moving forward, it is essential for agencies and policymakers to conduct thorough evaluations, address accountability concerns, and prioritize accuracy to ensure the effectiveness of these systems in addressing gun violence.
