Presuming departments track complaint resolution outcomes, we should see the rate of "legitimate" cases go up. E.g., if 100 cases were filed, 50 frivolous, and the officer in question was sanctioned in 10 cases, that's a 10% rate. If the number of frivolous cases drops to 0, the "sanction" rate should double to 20%.
