In April 2008, The Orange County Register published a bombshell of an investigation about a license plate program for California government workers and their families. Drivers of nearly 1 million cars and light trucks--out of a total 22 million vehicles registered statewide--were protected by a "shield" in the state records system between their license plate numbers and their home addresses. There were, the newspaper found, great practical benefits to this secrecy.
"Vehicles with protected license plates can run through dozens of intersections controlled by red light cameras with impunity," the Register's Jennifer Muir reported. "Parking citations issued to vehicles with protected plates are often dismissed because the process necessary to pierce the shield is too cumbersome. Some patrol officers let drivers with protected plates off with a warning because the plates signal that drivers are 'one of their own' or related to someone who is."
The plate program started in 1978 with the seemingly unobjectionable purpose of protecting the personal addresses of officials who deal directly with criminals. Police argued that the bad guys could call the Department of Motor Vehicles (DMV), get addresses for officers, and use the information to harm them or their family members. There was no rash of such incidents, only the possibility that they could take place.
