Well, I'd suggest a better system. It's still two tiered access (MANDATORY to reduce abuse), but a little more flexible. This is obviously a spit-ball solution with lots unverifiable of gaps.
A: Regular access. The request is sent to dispatch with a request for information and a small snippet of information of why the request is prescient now. If used through a device (license plate scanner?), the brief summary of the owner and 'risk factor' can be returned without any second tier access. If more information is necessary, a person (higher ranked officer, etc..?) then verifies the request and accepts the request. All of this is logged for audit in perpetuity.
B: Urgent access. Flag the request as immediate and emergency request for information. Once the emergency is resolved, the officer is then required to fill in a much more thorough document which requires several auditors to verify that the urgent access was merited and that it was used effectively. If used improperly, the officer could be censured/fired per department policy.
