>I think 2-5 are pretty unlikely and/or impractical given the conflicting demands on officer time in the real world.

Respectfully, you don't seem to have any experience with law enforcement or military. 2-5 happen routinely.

>There are 10,000 ShotSpotter events a year.

And that is a separate issue of capacity vs demand. Nevertheless, a system like ShotSpotter, when paired with resources and a triage system, is a very real augmentation to law enforcement capacity.

The problems with SpotShotter are completely separate from this. That's precisely why law enforcement seems to want it so badly.
