“Auditors studied ShotSpotter’s accuracy over several months in 2022 and 2023. When it was performing at its best, only 20 percent of ShotSpotter’s alerts actually revealed shootings, they found. Often, it did even worse. Of the 940 alerts officers responded to last June, only 13 percent corresponded to confirmed shootings.
And in 2022, the audit found, the system also failed to detect more than 200 real incidents of gunfire in Manhattan.”
