Editorial: If ShotSpotter constantly misfires, what’s Chicago getting for its $33 million? – Chicago Sun-Times*

"Police officers responding to calls from ShotSpotter, according to the study, report no evidence of a crime 86% of the time...we don’t like the notion that officers are being sent into neighborhoods thinking there is a dangerous emergency when, in reality, the call might have been triggered by noises misheard as gunfire by ShotSpotter. That can, in itself, create a tense situation."
