We Tracked the Secret Police Microphones Hidden Everywhere

ShotSpotter microphones are controversial surveillance devices designed to alert authorities to gunshots.

WIRED obtained leaked documents detailing the locations of over 25,500 of these devices, and what we learned abut how and where they’ve been deployed may surprise you.
