When gunshots ring out on America’s streets, bystanders face an instant, high-stakes dilemma. Do I call the cops? Were those even gunshots? (Maybe it was just fireworks.) Every moment of hesitation risks a delay in medical treatment or gives a suspect extra time to escape. But a high-tech solution to the problem has ignited a fresh round of controversy in cities across the nation. Law enforcement officials in states including New York, Georgia, California, Michigan and Virginia have credited one system with helping them make arrests and alerting them to gunshots that would have otherwise gone unreported.

The system – part of an arsenal of police surveillance technology advocates have warned about like license plate readers – is a network of audio sensors designed to record the sound of gunshots and tell authorities where the shots were fired. That’s where the problems start. The technology has faced a host of controversies: concerns over privacy and eavesdropping; complaints about accuracy; and even reports of many devices being installed in the wrong places.

In San José, California, and Champaign, Illinois, officials stopped using the system after finding it was much worse at detecting gunshots than the company claimed. In Jackson, Mississippi, some of the devices were installed on private property without the owners’ consent and left in place despite the city’s request to remove them. And in Roanoke, Virginia, the city removed the detectors after a botched rollout unsettled residents.

One of those devices was mistakenly installed in Kaitlyn Vaughn’s yard, where her children play. “I feel like everyone should have a right to privacy in their own home, and it makes you feel really vulnerable when you don't know if someone's listening all the time or not,” Vaughn said. “You don't have to be doing something wrong to want to have a private space.”
