Being skeptical of face value claims makes sense if they have never been used before. But, they've been in place in some cities since before 2000 and after searching I'm still not aware of any incident audio from it was used that didn't have to do with a gunshot.
Looking into it more all the cases of audio being used in court, that was not audio of gunshots, was audio immediately after a gunshot. Spotshotter is open about recording that and it seems completely reasonable to me this audio should be used.
What's most boggling to me about the criticism is Albuquerque apparently has 10,000 cameras law enforcement has access to. I know we likely disagree on the usefulness of those, but if you are privacy concerned why would shotspotter even be on the same level of concern as cameras that don't need a gunshot to start filming?
