      So we need to know both the range and the false positive rate, as well as the response

      • are they deployed so the only places in range of detection are non-white areas?
      • is there a high rate of false positives that somehow is worse in non-white areas?
      • is the response different in non-white areas vs white areas?
      • does the response specifically target non-white people in the target area?

        I’d imagine there’s a higher prevalence of gunshots in the non-white areas so more mics are placed there.

      Part of the problem is that there’s other loud noises that sound like gunshots like a car backfiring.

          There may be a typical distinctive range but it isn’t a range unique to firearms. There’s also real world variables at play here such as gunshots outdoors vs indoors that’d force them to broaden that range leading to more false positives.

              Way too many variables. Are you shooting 9mm, 45, .338 Lapua, .22lr? Are you shooting from a 9 in barrel, a 16 in, a three inch? Are you using a muffler? What brand and type? What is your range to the gun shot? Is the bullet supersonic or subsonic? Does the roofers hammer make a sound that falls inside the wide range of noises? There is no way to make an accurate profile for gun shot noise.
