No, these numbers are meaningless without a null hypothesis to compare them to. If you stop random people in the monitored areas, at the right time of day, how many guns do you find?

You need cause to investigate someone. So sounds like even if shot spotter is not accurate, it’s still effective. Criminal is a criminal.

  Not everyone who is searched has commited a crime. See, e.g., this paper: https://conrad-miller.github.io/qjab018.pdf https://conrad-miller.github.io/qjab018.pdf

    You are not required to have committed a crime to be legally searched. If you're fleeing the area where gunshots have been reported, it's not unreasonable to search you.

  So to rephrase your argument, shotspotter allows police to arrest people with made up evidence. You say that is a good thing, because they were criminals anyway. You have an interesting concept of the rule of law.

    Not OP, but probable cause is not "made up evidence." If there's a report of a noise that sounds like a gunshot, and that results in a search of people who are running, and that search finds an illegal gun, that's reasonable.

      Why does this scenario presume that people are running? Even with this technology, it seems exceedingly unlikely that police are arriving on the scene within seconds of a possible gunshot; it's much more likely that they're corralling bystanders and frisking them.

        And why does your scenario presume that the situation is completely cold? The average police response time in Chicago is 5-6 minutes[0]. I'm going to bet that active shootings are on the fast side of the average. Having lived in Chicago for 7 years, I can tell you there are areas where you regularly see police patrolling. 0. https://mediaprogram.maps.arcgis.com/apps/Minimalist/index.html?appid=a12f63bb39af4c65912e034688bfb3a1 https://mediaprogram.maps.arcgis.com/apps/Minimalist/index.h...

        Not completely cold. I would just be mildly surprised if someone lingered around for 5-6 minutes and then ran. In any case, this is all supposition. We aren’t being allowed to review the actual evidence, so for all I know SpotShotter is just telling the police what they’re asking it to.

      I'm sorry, what's the premise here? People don't run away from random gunfights that happen on the street? Honestly, I feel like it's more likely that a random person is not involved if they are running.
