The locations of microphones used to detect gunshots have been kept hidden from police and the public. A WIRED analysis of leaked coordinates confirms arguments critics have made against the technology.
The only problem ShotSpotter solves is not enough public money into private hands. What information does it actually give the police, even assuming that it is 100% accurate?
At a certain time and place a gun was fired. Great? Who cares. That isn't worth $1million/mo.
If there are 3 people in the general location and time that a gun was fired, what has shotspotter done to help?
Maybe I missed it but the article actually does not tell/show you where these secret locations are. A red dot on a map that doesn't zoom in well enough is kinda useless.
