The article suggests that the police can go to Shotspotter and ask for some other convenient sound or perhaps even no sound at all(?) to be retroactively reclassified as a gunshot where they wanted it to be, so they can then use that as an excuse to stop the person they already wanted to or already did but didn't have a valid reason to. That's worse than random and worse than a policeman honestly mistaking a backfire for a gunshot.
