Maturity? You see this as a prank? I think you're on the wrong foot here. The premise of the cameras was not that they were there for decorative effect as some sort of symbol to be vandalized. I see it as a majority of the Chicago police force destroying evidence and equipment necessary to investigate their actions. This is open rebellion with the intent to escape justice - though for what crime specifically we may never know. Any proveably "deliberate" tampering should end in a firing, revocation of pension, and then court case brought against them. Any deliberate tampering during which the officer sustains a complaint against them? Enter this into presumptive evidence against the officer and recommend prosecution. We started monitoring the officer because it turns out they can't be trusted as much as we thought - slipping our monitoring and destroying our property is an overtly hostile act, the same as openly slitting the tires of an Internal Affairs agent in the process of investigating the officer. To deter it in the future: ramp up the random checks (you did have random checks... right? I should be able to pick a random time and download footage) and enter in punitive fines for poorly maintained or operated cameras; Raise salary slightly to make it budget-neutral, but pay for prompt repair first.
