To tech for aid against violence
Sensors in test effort give alert on gunshots
In an effort to deter gun violence, Las Vegas police have implemented acoustic technology that alerts authorities to gunshots.
Metropolitan Police Department officials are testing the technology in a yearlong pilot program at an undisclosed location in northeast Las Vegas, Deputy Chief Chris Jones said at a Thursday news conference. Citing reduced response times, more accurate reported gunshot locations and better officer situational awareness, police said they hope the technology will help reduce violent crime in the Las Vegas Valley.
“We as a community cannot be apathetic to gun violence,” Capt. Jim Larochelle said.
Larochelle heads Metro’s Northeast Area Command, where police have installed multiple acoustic sensors sensitive to the sound of gunshots. Larochelle said the sensors’ locations, which were not disclosed Thursday, were determined based on areas where police receive high numbers of reported gunshots.
Plans are in places to add sensors in the southeast and south-central command areas.
Through the company Shotspotter, the sensors listen for loud pops or booms to indicate gunshots, and if enough sensors are activated, a notification is made to an acoustic expert at the Shotspotter headquarters. The expert determines whether the gunshots detection is legitimate, and if it is, alerts Metro with the time, number and location of the shots.
Metro said the system can reduce response times for police heading to the reported gunshots to about 45 seconds, faster than it takes for somebody to decide to pick up the phone and try to determine where the shots were fired.
The sensors triangulate the location of the shots, which Metro said increases accuracy.
According to a Shotspotters 2015 study of 46 cities using the technology, year-over-year shooting rates declined about 13 percent.
Police hope the system alerts officers of gunfire regardless of whether anybody calls police.
He encouraged people to continue calling 911, as the sensors are meant to help police, not replace people calling in shootings.
Driving force
Clark County Commissioner Marilyn Kirkpatrick was the driving force behind the pilot program in Metro’s Northeast Area Command, which includes an area she represents, officials said. It’s part of her Pathway From Poverty initiative, which seeks to provide economic, educational and social support to impoverished areas of the northeast valley.
She said the Shotspotter system came together in the past six months and was a final piece to the initiative.
The commissioner representing District B said the cameras and audio sensors can address community members’ concerns about unreported gunfire.
She said the area with the initiative has a low average income and little home ownership.
The technology was funded through $500,000 in grant money from the Friends of Las Vegas Metropolitan Police Department Foundation and the University of Nevada, Reno’s Cooperative Extension program.
The decision to implement the gunshot sensor system wasn’t a result of the Oct. 1 mass shooting on the Strip, Larochelle said, later adding police could examine the viability of expanding the sensors to the Strip and Fremont Street, depending on the pilot program’s success.
The technology is used in more than 90 cities or counties in the United States and its territories. Among them are Chicago, San Francisco, Kansas City and Denver.
