I mean brass can be crazy hard to find, I'd bet if you did a geocaching experiment with brass picking a random spot within shotspotter's accuracy tolerances, you'd find the casing less than 50% of the time. Add in an hourly employee that is in no way motivated to find the casing and you'd prob drop to 10%.

And that’s assuming ideal conditions. Criminals don’t always leave their brass lying around if they can avoid it, after all.

Hah yea that's fair.

Though at the end of the day it doesn't really matter. The brass I mean. Finding brass or not finding brass doesn't exactly help catch or prosecute someone shooting a gun illegally. The whole point was to more quickly catch crimes in progress, and it doesn't seem like that's working.
