Have you tried zooming out on the stats at all, or analyzing any other variables? You realize there was a crazy spike in crime in the wake of the pandemic, right? Certainly a reversion to the mean might happen alongside the implementation of cameras.

My own city's police (Redwood City, CA) credited Flock cameras with an increase in the clearance rate from 12% to 13%. Pardon me if I don't go out and celebrate.
