Chicago is letting the ShotSpotter contract expire instead renewing this year after the data revealed that it did not have any positive effect on crime reduction.
I think that's because our police force is incompetent though. Shotspotter may very well suck but if the police cant solve shit either way its not shotspotters fault. Murder has a 5% clearance rate here
