We can ddos these things with enough acorns

There are more details from the author on The Orange Site. Here's something in particular that stood out to me:

The ECC dispatches the call as a priority 2. P2 is high enough that a ShotSpotter report will "bump" most calls for service except for a caller on the line violent crime in progress. When the officers arrive at the reported location, they make a brief assessment and search the area for suspects or victims. If no suspects or victims are found, a Crime Scene Technician is dispatched (often later as they will wait for daylight) to search the area for evidence such as spent shell casings.

later on...

One of the major criticisms of the ShotSpotter system in Albuquerque is that it results in a relatively large volume of P2 calls that delay police response to most other calls for service. During the worst of the understaffing, I was told that some officers in high-crime areas like the International District spent a large portion of their total shift following up on ShotSpotter activations while there were multiple P3 calls queued.

This situation reminds me of the Super Troopers bear scene, where the main characters distracted the city police in order to perform a heist on the station. An organized effort could use the ShotSpotter system to distract the police away from other calls or areas of the city.
