"Shots Fired, Pinpointed and Argued Over"

From the New York Times. In part:

A technician quickly focused on the computer screen, where the words “multiple gunshots” appeared in large type. She listened to a recording of the shots — the tat-tat-tat-tat-tat of five rounds from a small-caliber weapon — and zoomed in on a satellite map to see where the gun had been fired: North 23rd Street in Milwaukee, 2,200 miles away.

The detection system, which triangulates sound picked up by acoustic sensors placed on buildings, utility poles and other structures, is part of a wave of technological advances that is transforming the way police officers do their jobs.

But like other technologies, including license plate scanners, body cameras and GPS trackers, the gunshot-detection system has also inspired debate.
