ShotSpotter installs its acoustic sensors on buildings, telephone poles and street lights. “The evidence that we’ve produced suggests that the technology does not reduce firearm violence in the long-term, and the implementation of the technology does not lead to increased murder or weapons related arrests,” said lead author Mitch Doucette. It found that the technology didn’t reduce gun violence or increase community safety. Researchers who took a look at ShotSpotter’s impacts in communities where it is used came to a different conclusion. One study published in April in the peer-reviewed Journal of Urban Health examined ShotSpotter in 68 large, metropolitan counties from 1999 to 2016, the largest review to date. “ShotSpotter has turned into one of the most important cogs in our wheel of addressing gun violence,” said Toledo, Ohio Police Chief George Kral during a 2019 International Association of Chiefs of Police conference in Chicago. Law enforcement officials say it helps get officers to crime scenes quicker and helps cash-strapped public safety agencies better deploy their resources. The system is usually placed at the request of local officials in neighborhoods deemed to be the highest risk for gun violence, which are often disproportionately Black and Latino communities.
The technology, which has been installed in about 110 American cities, large and small, can cost up to $95,000 per square mile per year. Police chiefs call ShotSpotter a game-changer.
