I live in a city where ShotSpotter is often used to detect gun violence and it seems, at least from local reporting, that it's often accurate in detecting gunfire and often finds victim(s) on the scene, often uncooperative with police. In so far as I can tell, it seems to be doing its job, though I understand there are several institutions here which obviously are not trustworthy.

This is a classic example of the survivorship bias: local reporting doesn't report on the unknown proportion of cases that are false positives or wild goose chases. It also doesn't divulge where the police are putting their thumb on the scale by having ShotSpotter edit the "evidence" after the fact, as is alleged in this case.
