You can listen to the ShotSpotter audio from that incident here - https://www.chicagocopa.org/case/2024-0002095/

I see nothing wrong done by ShotSpotter.

It accurately reported the location of a noise that sounded like gunfire.

What is timely about this?

Do you want the police to not investigate gunshots? I don't care about how they approached the scene, their training has nothing to do with ShotSpotter which is the discussion at hand.

Also fireworks are illegal to set off in Chicago so no legitimate activity was interrupted.
