As Daniel from work said in the email, “back to bows and arrows” and I would like to add knives and clubs:
A new technology called ShotSpotter enables law enforcement officials to precisely and instantaneously locate shooters, and it has been quietly rolling out across America. From Long Island, N.Y., to San Francisco, Calif., more than 60 cities in the U.S. have been leveraging ShotSpotter to make their streets safer.
ShotSpotter relies on wide-area acoustic surveillance and GPS technology to triangulate the source of gunshots. Sensors are fixed to buildings and poles to provide coverage over a fixed area. With audio-analysis software, it can identify whether a shooter is stationary or moving — meaning police officers can be equipped with information on the speed and direction of, say, a vehicle from which a shot was fired.
It can also “hear” the acoustic signature and distinguish between calibers and types of firearms. Similarly, it can hear different explosions and classify them, from vehicle backfires to fireworks to bombs.
The ShotSpotter Gunfire Alert system then relays the location and data to the police or a dispatch computer within moments, enabling a more rapid response time for both police and first responders.
The best part: ShotSpotter works. It’s accurate to 10 to 15 feet, and some police departments are reporting accuracy to within five feet. In Long Island’s Nassau County, gun violence was reduced by a whopping 90 percent at the close of this year’s first quarter.
It would be interested to see if the total violence and not just “gun violence” was reduced. I’m immediately suspect when careful wording such as that in the last paragraph is used.
