Police warned on plate covers. Apparently there are license plate covers that make it difficult for the new traffic cameras to catch violators. “John Pinero, president of Performance Auto Care Center, which sells the majority of the plate covers on Oahu, says the Eliminator does work, though it is ‘not 100 percent.’ Since Pinero began selling the plate covers on Dec. 10, he said several police officers have come in and at times bought ’20 to 30′ covers each.” Hmmm.
