In addition to data Creation and Reading, we also have to address Update and Delete. Do they change the data or delete "special" cars or "special" events. If there are any exceptions to collecting and storing the data, we can't trust it for much of anything: maybe the license plate entry was changed to a different license, maybe seeing a license at a location was added to the data, maybe other suspects are ruled out because data was deleted. And there will absolutly be exceptions: undercover officers, the presidents motorcade, people with stalkers, etc...
